National coal mine installs inspect bureau to pound the ground to press the announcement that prevention and cure works about strengthening a colliery
Each produce coal province, municipality, municipality directly under the Central Government and Xinjiang production to build corps colliery safety to superintend management department of industry of branch, coal, each provincial colliery safety is censorial bureau, management board of colliery of judiciary directly under, about central enterprise:
For industry of coal of a surname of dragon of group of mining industry of mouth of dragon of the sources of energy of deep derive Shandong " 10? 20 " wait for concussion ground to press accident lesson, advance fulfil " colliery safe practice " " ground of concussion of colliery of prevention and cure presses detailed rules " wait for regulations standard requirement, be on guard effectively to pound the ground to press an accident with colliery of determined keep within limits, strengthen a colliery to pound the ground to press job of prevention and cure to inform as follows now:
One, ground of aggrandizement colliery concussion presses fountainhead prevention and cure
1. pounds what the ground controls mine strictly to limit. Colliery enterprise must strict according to " colliery safe practice " " ground of concussion of colliery of prevention and cure presses detailed rules " it is dangerous that the requirement begins concussion tendentiousness appraisal and concussion sexual evaluation, seasonable, accurate limit concussion ground to control mine. Coal cliff body has happened to shake strongly all round colliery well alley or working face, instantaneous bottom (side) of the dynamical phenomenon such as eject of cliff of beat, coal, maintain directly control mine to pound the ground. After colliery happening pounds the ground to control dynamical appearance, ought to superintend branch and safety of colliery of place where troops are stationed to apanage colliery safety instantly censorial orgnaization report. The technology that assumes assessment of concussion tendentiousness appraisal and concussion danger sex serves an orgnaization, want to ask strictly according to standard and program, issue opinion of appraisal, evaluation, be in charge of as a result to appraisal, evaluation.
2. controls concussion ground strictly to control mine scale of production. Concussion ground presses mine to ought to be pressed strictly undertake designing according to relevant provision, scale of production must not exceed 8 million tons / year, nuclear increase production is not gotten after building can. When blame concussion ground presses mine to upgrade to control mine to pound the ground, ought to weave mine prevents strong design, and according to prevent strong demand to undertake mine productivity check and ratify.
3. is carried out strictly defend strong measure actively. Concussion ground presses mine to ought to be carried out strictly " colliery safe practice " the 231st regulation that works about tunnel is decorated and excavating, continue of reasonable arrangement excavate. Collect deep the more than 400 meters mine that controls coal-bed without concussion ground, decorate in coal-bed and order of working surface excavate, tunnel stay with column of timbering, coal set, when the design such as excavate exercise, ought to prevent stress concentration, prevent unreasonable exploitation to bring about concussion ground to press an accident to happen.
2, aggrandizement concussion ground presses mine tunnel timbering
Form of timbering of tunnel of 4. logical choice and parameter. When the tunnel that driving carrying coal on the head holds in the palm by thick coal-bed edge chooses timbering of anchorage lever anchor cable, anchorage shank diameter must not be less than 22 millimeter, must use full-length or lengthen is anchorage solid, anchor cable diameter must not be less than 20 millimeter, extend rate must be more than 5% , system of timbering of anchorage lever anchor cable ought to use metal strip (channel) with braid gauze to protect a watch, ply of anchorage lever tray is not less than 10 millimeter, ply of anchor cable tray is not less than 20 millimeter, must not use reinforcing steel bar ladder and solder net of reinforcing steel bar serves as the component that protect a watch. Tilt the tunnel of coal-bed of edge top driving that reachs above, high side side must increase anchor cable timbering. When coal-bed bury deepness exceeds 800 meters, bottom of thick coal-bed edge holds the tunnel of driving carrying coal on the head in the palm, and encounter roof broken, drench the water, tunnel that crosses too fault, old empty division, tall stress region ought to use anchorage rod anchor cable and can shrink bracket is compound timbering form, strengthen timbering and monitor from the layer into travel roof, to already digging tunnel, ought to adopt right timbering kind to undertake filling strong timbering, prevent to pound the ground to press accident of as compound as tunnel roof fall calamity to happen.
5. strengthens timbering of excavate working face. The export of safety of coal mining working face that has concussion risk and limits of timbering of tunnel joint lead must not be less than 100 meters, put together is collected the safety of coal mining working face that reachs above to pound dangerous area waits in put working face carrying coal on the head or be being had exit and limits of timbering of tunnel joint lead must not be less than 150 meters, lead timbering is preferential use a stack type bracket or move oneself the frame type such as bracket of type hydraulic pressure defends concussion stand. Working face of coal alley driving is rear the area that reachs above to pound danger waits to ought to strengthen timbering in having, preferential use a stack type bracket or move oneself bracket of type hydraulic pressure.
3, aggrandizement is prevented strong monitor and measure is fulfilled
6. builds sex of perfect concussion danger to monitor early-warning system. Concussion ground presses mine to must build concussion danger sex to monitor, real time early-warning, attemper deal with and treat result feedback institution, deploy professional technology personnel to be in charge of monitoring work with early-warning, daily condition of the monitoring data that controls dangerous area to pounding the ground, production undertake integration analysis grinds sentence, forecast pounds dangerous level, the work out prevents daily of the strong analysis that monitor, the newspaper prevents strong controller, chief engineer, mine to grow via the colliery sign, tell relevant unit in time (branch) with personnel.
7. aggrandizement prevents strong step to fulfil. Concussion ground presses mine to must be deployed prevent strong orgnaization, major technically to prevent strong team, strict organization is carried out defend strong measure, build prevent strong step to carry out record stage Zhang, assure to defend strong process but date from. The main controller of colliery enterprise, technology chief ought to every quarter prevents those who develop measure each at least one times to fulfil a circumstance to spot examination. Coal-master wants chief and chief engineer to ought to check each at least one times every months to prevent those who develop measure to fulfil a circumstance to the spot.
4, aggrandizement production work organizes management
8. implements system of admittance of personnel of concussion danger danger zone strictly. Concussion ground presses mine to ought to build system of admittance of staff of concussion danger area, execute hang out one's shingle management of the member that be restricted, coal mining and driving ought to make clear the time that stipulates personnel is entered, area and number in work rules. The driving working face that pounds the ground to press coal-bed enters personnel to must not exceed 9 people inside 200 meters of limits, stoping working face and two alley lead enter personnel to must not exceed 16 people inside 300 meters of limits. Intelligence of working face of big thrust wide coal mining changes unmanned exploitation technology and driving working face remote hold accuse driving technology.
9. restricts activity in parallel of much working procedure strictly. When coal mining working face and driving working face implement the measure that see danger (contain beforehand discharge presses measure) , must evacuate and the staff that prevent strong step construction to have nothing to do. Withdraw the least space of the place that see danger: Region of danger zone of strong impact danger must not be less than 400 meters, region of danger zone of medium concussion danger must not be less than 300 meters, other area must not be less than 200 meters; Tunnel is maintained must not wait for working procedure activity in parallel with driving, coal mining, the labor that should use alone construction organizes means.
10. is strict according to prevent strong demand to organize production. Concussion ground presses mine to ought to build production to organize requisition system, manufacturing organization requisition prevents strong department basis by the colliery of each excavate working face prevent strong demand and concussion danger sex to monitor grind sentence a result to weave, tunnel of specific provision driving and coal mining working face most footage of the top class in a kindergarten, day footage and average day footage, sign up for a colliery to prevent strong controller and main controller to examine and approve, forbidden exceed requisition ability to organize production.
5, aggrandizement concussion ground presses mine to superintend censorial
11. superintends censorial object mainly certainly. Various colliery safety superintends censorial branch to want to be fulfilled seriously superintend censorial duty, the coal mine concussion ground controls prevention and cure to examine content as the key, examination colliery enterprise and colliery pound what the ground controls liability of main body of prevention and cure to fulfil a circumstance, examination colliery is carried out " colliery safe practice " " ground of concussion of colliery of prevention and cure presses detailed rules " etc regulations standard, fulfil each concussion ground to press safety of prevention and cure technical measure circumstance, to area under administration inside all mine that ought to undertake coal cliff pounds tendentiousness appraisal and dangerous sex evaluation undertake discharging checking.
12. is investigated lawfully break the law violate compasses act. Colliery safety superintends censorial branch to discover a colliery " it is dangerous to have concussion ground is pressed, did not take effective measures " great and safe hidden trouble, ought to according to " the special provision that the State Council produces safe accident about preventing a colliery " and " the colliery is great hidden trouble of manufacturing safety accident decides standard " undertake condemnatory.
