Through the new practice, and summarizes some of the measures and methods of preventing gas, the construction of a new outburst reference. Keywords: New; gas; Outburst; governance 1 of the problem in the mine during the construction period, main and auxiliary, local fan ventilation shaft are used for the wind from the ground , with the construction of tunnel length, depth increase, increasing the amount of gas emission, in particular,<a href="http://www.mac-cosmetics-cheap.com" target="_blank" class="postlink">mac beauty powder</a>, into the 6 S102 track, trough the construction of transportation, gas overrun phenomenon often occurs, and the three adit and the rail transportation have to be smooth Coal Uncovering the work carried out. Seriously affected the progress of the project, brought to safety hazards. To ensure safety in production, to explore, volleyball, gas drainage and other comprehensive measures. 2 gas control measures 2.1 indicators measured in the main shaft through the driving face 6 of coal seam +1801 see the point of sampling,<a href="http://www.maccosmeticsretail.com" target="_blank" class="postlink">MAC Cosmetics Discount</a>, sent to China University of Mining (Beijing) for coal and gas outburst hazard index determination. Return air shaft in the central coal exposed before,<a href="http://www.cosmetic-mac.com" target="_blank" class="postlink">MAC Cosmetics Discount</a>, the original 6 in the coal seam gas pressure measurement, the pressure reaches 3.1Mpa (the critical value of 0.74Mpa). S102 in 6 orbital trough construction, the return air flow of gas by 0.9% -1.4% concentration, gas emission in 2.1-3.8m3/min, k1 value forecast 5.83ml/minl/2. Identification results of the above analysis highlights the danger of large coal mine,<a href="http://www.toryburchshoesonsale.com" target="_blank" class="postlink">tory burch shoes</a>, must find the seam sensitive indicators highlight the risk prediction, strictly enforce the \ 2.2 organizational structure and management system with adequate ventilation,<a href="http://www.p90xdvd-wholesale.com/products_new" target="_blank" class="postlink">p90x wholesale</a>, gas management, conflict prevention, drainage, dust-proof security monitoring and professional team of engineers and technicians. During construction to protect the mine ventilation gas management, formulated the \safety management system. 2.3 building to strengthen local ventilation early in the ventilation system has not formed before the main and auxiliary adit return slope and 6 S102 rail transport trough are made of five high-power driving face 2 × 45KW for air volume 750m 3 / min-300m 3 / min, air pressure duct for the 400-6500P large diameter to meet the needs of the construction of five heading face. Local ventilation to achieve \ 2.4 Gas Management establish and improve the gas management system, strictly implement the \Construction safety management from the management of closed loop control system, the establishment of the gas management system can be effectively implemented in the long-term mechanism. 2.5 Monitoring according to the actual situation of high-gas coal mine, built the initial wells, installation of methane on the heading face of wind power and methane alarms power locking device device. Lord, Vice adit through the central return air shaft after the mine safety and production monitoring and control equipment, type of coal used KJ95 integrated monitoring device. 2.6 to prevent the coal (rock) and gas outburst in coal mine exploration and geological data this does not provide the initial speed of coal seam gas irradiation, consistent coefficient of coal, coal porosity, gas pressure, the measured data. Analogy to similar mines. Determine the occurrence of coal mine gas outburst likely. And in accordance with the ongoing management of outburst. 2.6.1 geological work and the work of mining gas to prevent tunneling process, the error through small kiln, the old Lane, geological tectonic zone (faults, fracture zones, the anticline axis, Change with coal), Mine exploration in the original report on the basis of geological exploration work to further identify the geological situation. 2.6.2 adhere to the \The coal seam gas content, gas pressure, f values and coal gas permeability coefficient of basic parameters. In order to prevent sudden technical measures for the development of a reliable basis. <br /> More articles related to topics： <br /> <br /> <br /> <a href="http://amnhacvietnam.forumup.us/viewtopic.php?p=1750&mforum=amnhacvietnam#1750" target="_blank" class="postlink">MAC Cosmetics Cheap On the theory of urban design</a> <br /> <br /> <a href="http://www.rosj.fora.pl/romet-komar,13/mac-concealer-concrete-floor-cracks-and-fill-crack,198.html#250" target="_blank" class="postlink">mac concealer Concrete floor cracks and fill crack</a> <br /> <br /> <a href="http://forum.kisielewski.com.pl/viewtopic.php?p=16139#16139" target="_blank" class="postlink">p90x workout schedule Wenchuan _4147</a></span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/xeon/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
