摘要
煤矿开采势必造成上覆岩体的运动和破坏,综采工作面导水裂隙带高度成为煤层开采上覆含水层建立水力联系的关键,制约着矿井安全开采。基于潞安集团余吾煤矿厚煤层采区矿井地质和水文地质条件,分别通过经验公式计算结果、相似材料模拟结果和计算机数值模拟结果,结合矿井相邻采区工作面导水裂隙带实测数据,采用多数据融合线性回归分析,确定南五采区导水裂隙带高度值为103.1~113.9 m,为余吾矿井安全生产和煤层顶板支护提供了科学依据和参数。
The mining of coal mine is bound to cause the movement and destruction of overlying rock mass.The height of water flowing fractured zone in fully mechanized mining face has become the key to establish hydraulic connection of overlying aquifer in coal seam mining,which restricts the safe mining of coal mine.Based on the geological and hydrogeological conditions of the thick coal seam mining area of Yuwu Mine of Lu'an Group,through the empirical formula calculation results,similar material simulation results and computer numerical simulation results,combined with the measured data of the water-conducting fracture zone in the working face of the adjacent mining area of the mine,the linear regression analysis of multi-data fusion was used to determine the height of the water-conducting fracture zone in the south fifth mining area.The value was 103.1~113.9 m,which provided scientific basis and parameters for the safety production and coal seam roof support of Yuwu Mine.
