根据屯留矿1202工作面的具体地质条件,通过理论分析、数值模拟和现场实测相结合的方法,确定了裂隙带的高度范围。通过数值模拟研究了不同位置时高抽巷的围岩变形量,确定了高抽巷布置的合理位置。现场矿压观测结果表明,该高抽巷的布设位置合理,巷道变形量对抽采瓦斯的影响不大。
According to the specific geological conditions of the 1202 working face of Tunliu Mine, the height range of the fractured zone was determined through a combination of theoretical analysis, numerical simulation and field measurement. Through the numerical simulation, the deformation of the surrounding rock of high pumping lane at different positions was studied, and the reasonable position of high pumping tunnel was determined. The results of on-site rock pressure observation show that the layout of high-pumping roadway is reasonable and the influence of roadway deformation on gas drainage is insignificant.
