摘要
协庄井田目前开采下组煤13煤层,其开采受徐、奥灰水威胁。为研究断层对矿井底板突水的危险性的影响,根据13煤层的地质资料,从断层的长度、落差及交点和端点的个数等特征入手,绘制断层影响因子等值线图,并根据其分布特征进行突水危险性分区,为该矿受徐、奥灰水威胁的下组煤安全开采提供基础理论资料。
Xiezhuang coal mine is mining the lower coal seam 13,which are seriously threatened by the Xujiazhuang limestone water and Ordovician limestone water. In order to study the effect of fault to the coal mine inrush risk, according to the geological data of coal seam 13, starting with the characteristic of the length of the fault, drop, the number of intersection point and endpoint, we draw the fault impact factor contour map, and according to the distribution characteristics, divide into different regions of water inrush risk, which provide basic theoretical information for the safe mining of the lower coal seam under the threat of the Xujiazhuang limestone water and Ordovician limestone water.
