| 摘 要： | 针对开滦东欢坨矿开采煤８诱发的顶板涌（突）水问题，首先采用五个物理场的多源地学信息复合研究方法对煤８顶板充不含水层进行了富水性综合分区。此外，在充分分析煤８至顶板充水含水层间岩段的岩性特征基础上，将据《煤矿安全规程》计算出的导水裂隙发育高度进行了全方位的岩性场定性构正，并编制了煤８回采冒落安全性分区图。在此基础上，耦合叠加分析煤８回采冒落安全性分区和其顶板充水含水层的富水性分区结果，对东欢坨矿煤８ |

| Abstract: | Based on an overlapping principle of multiple geological information,this paper divides firstly roof water filling aquifer into different water enrichment subareas,in the light of roof water bursting problems resulted from mining coal seam No.8 in Donghuantuo coal mine,Kailuan,China.In addition,according to analyses of lithologic features for rock bed between the coal seam No.8 and the roof aquifer,the paper re corrects water conduction heights calculated with special regulation which is short of consideration of the lithologic features,and draws up a roof falling safety division map.On the basis of the water enrichmental and the safety division map,a scientific safety evaluation system for the roof water bursting condition during mining coal seam No.8 is established,and a division scheme for the condition is also put forward in the paper.Finally,dynamic water inflows for working faces No.2086 and No.2188B are predicted by applying Visual Modflow. |
