永盛煤矿南井主采煤层煤与瓦斯突出危险性评估
Risk Assessment of Coal and Gas Outburst in Main Coal Seams of Yongsheng Coal Mine South Shaft
摘要
Abstract
Selecting the main mining 2# and 9# coal seams in Yongsheng coal mine south shaft as a research object, based on the maxi- mum gas pressure of the coal seam and the test results of coal sample gas parameters, its outburst risk is assessed. The test results showed that the single indicator and composite indicator of outburst risk in 2# and 9# coal seams of Yongsheng coal mine south shaft ex- ceeded the critical value regulated in coal and gas outburst prevention provisions. There is no obvious fault structure through the ground in filed areas ; gas is difficult to release from the fault structure. Gas occurrence conditions are good with deep buried coal and poor per- meability rock in overlying rock. The analysis determined that the 2#, 9# coal seams in Yongsheng coal mine south shaft were the coal and gas outburst coal seam.关键词
