摘要
河南省某煤矿目前处在普查阶段,尚未进行开采,针对可采煤层开展区域突出危险性预测,可发现突出危险煤层,指导未来煤矿安全生产。根据突出危险区划理论,针对河南省某煤矿可采煤层区域突出危险性预测。首先计算可采煤层发生突出瓦斯压力最小值Pmin及其对应的煤层瓦斯含量W0,按照以安全为基础,同时考虑矿井生产实际情况的原则,选择煤层瓦斯含量指标作为区域划分的指标:当煤层瓦斯含量W<W0时,才能划为无突出危险区,否则就划为突出危险区。结果表明,该区的可采煤层二1、二2均为突出危险煤层,一3为无突出危险煤层,为突出防治工作提供了指导作用。
This paper calculates the regional outburst danger of the minable coal seams in a coal mine in Henan Province based on the division theory of outburst danger. The minimum gas outburst pressure Pmi,, and gas content Wo are calculated. Gas outburst danger zone is characterized by W 〈 W0. From this calculation it is concluded that the minable seams II 1 and II 2 in this area are outburst danger seams, and I 3 isn＇t outburst danger seams, which provides guidance to the prevention and control of gas outburst.
