平舒煤矿15110工作面顶抽巷空间定位数值模拟研究

Study on numerical simulation of spatial location of roof extraction roadway in the 15110working face of Pingshu coal mine

高瓦斯工作面的瓦斯浓度频繁超限是制约安全高效生产的主要因素。基于阳煤集团平舒煤矿15110工作面实际工程地质特征,综合采用数值模拟和理论分析的方式,根据工作面回采时的采场应力分布特征并考虑岩巷掘进与经济成本等因素,为15110工作面顶板瓦斯抽采巷确定具体空间位置。

Frequent exceeding of gas concentration in high gas working face is the main factor restricting safe and efficient production. Based on the actual engineering geological characteristics of 15110 working face in Pingshu coal mine of Yangquan Coal Group, the specific spatial location of roof gas extraction roadway in 15110 working face is determined by means of numerical simulation and theoretical analysis, according to the stress distribution characteristics of working face during mining and considering factors such as rock roadway excavation and economic cost.
