随着开采深度的增加,高地应力显现,煤与瓦斯突出和冲击地压等灾害频繁发生。针对高地应力突出与冲击地压共存的情况下,如何采取有效防治措施成为迫切问题。为了减少高地应力下动力灾害的发生,平煤十一矿己16-17-22161工作面采取了本煤层抽放、煤层注水、深孔爆破等防治措施,取得良好效果,有效降低了煤与瓦斯突出及冲击地压发生的危险性。
With the increase of mining depth, the stress of the highland appears, and disasters such as coal and gas outburst and rockburst occur frequently. In view of the coexistence of high ground stress and rock burst, how to take effective prevention and control measures becomes an urgent problem. In order to reduce the occurrence of dynamic disasters under high ground stress, the prevention and cure measures of coal seam drainage, coal seam injection and deep-hole blasting have been taken in the face of No.16 Mine of Pingdingshan Coal Mine 11-17-22161, which has achieved good results and effectively reduced the coal and gas Prominent and impact on the risk of pressure.
