摘　　要：呼吉尔特矿区侏罗系深埋煤层顶板水害威胁区内矿井安全,开展覆岩导水断裂带高度研究尤为重要。以巴彦高勒煤矿为例,通过理论计算、数值模拟、相似材料模拟、现场实测等手段,对矿井3^-1煤层首采工作面进行顶板导水断裂带高度分析研究。结果表明:理论计算及方法存在一定的缺陷,不适用于本矿井导水断裂带高度预测;单回路双胶囊封堵压水测试方法在现场实测过程中具有较好的效果;对比分析数值模拟、相似材料模拟、现场实测得到的数据结果基本一致,综合平均各方法结果可得巴彦高勒煤矿3^-1煤层311101首采工作面顶板导水断裂带发育高度约为122m,按照采高5.3m计算,裂采比约为23倍,可作为矿井未来开采过程中防治水工作开展的参考依据。The water damage of the top of Jurassic deep buried coal seam in Hujiert Mining Area threatens the mine safety.It was particularly important to study the height of water flowing fractured zone in overburden strata.Take the Bayangaole Coal Mine as an example,through theoretical calculation,numerical simulation,simulation of similar materials,field measurement and other means,we analyzed and studied the height of 3^-1 coal seam roof water flowing fractured zone in the first mining face.The results showed that there were some defects in the theoretical calculation and methods,which were not suitable for the height prediction of water flowing fractured zone in this coal mine.The method of single loop double capsule sealing water pressure test had good effect in field measurement.The results of comparative analysis,numerical simulation,similar material simulation and field measurement were basically consistent.Based on the results of the average method,it could be obtain that the development height of roof water flowing fractured zone was about 122m in 311101 first mining face of 3^-1 coal seam of Bayangaole Coal Mine,and the mining ratio was about 23 times based on the mining height of 5.3m,which could be used as a reference for the water prevention and control in the future mining process.
