摘要:

为准确掌握红柳煤矿I04采区2煤采动范围内突水致灾的可能性,以关键层理论为基础,分析该工作面覆岩的稳定性和破断规律,并利用钻孔窥视法、分段注水法和数值模拟法对I040201综采工作面“两带”高度进行探测。研究结果表明:红柳煤矿I040201综采工作面垮落带高度约为54.40 m,断裂带高度约为98.12 m;I04采区2煤垮采比为10.46,裂采比为18.87;工作面采动造成的覆岩破坏未贯通安定组含水层。测试结果可为红柳煤矿采空区顶板管理、防水煤柱的留设,以及采掘部署和巷道支护等提供理论支撑和参考依据。

Abstract:

In order to accurately grasp the possibility of disaster caused by sudden water surge within the 2-coal mining range of the I04 mining area of Hongliu Mine, the stability of the overburden rock and the breakage law of the working face were analyzed based on the key layer theory, and a probing study was conducted on the height of the ″two zones″ of the I040201 comprehensive mining face by using the borehole peeping method, the segmented water injection method, and the numerical simulation method. The results show that the height of the collapse zone of I040201 comprehensive mining face in Hongliu Mine is about 54.40 m, and the height of the fissure zone is about 98.12 m; the collapse ratio of 2-coal in I04 mining area is 10.46, and the fissure ratio of 2-coal in I04 mining area is 18.87; the destruction of overburden caused by the mining of the face has not penetrated the aquifer of Anding Formation. The test results provide theoretical support and scientific basis for the management of the roof plate in the open area of Hongliu Mine, the setting of waterproof coal pillars, as well as the deployment of mining and roadway support.

Key words: overburden rock damage, disaster caused by sudden water surge, ″two zones″ of roof plate, segmented water injection, numerical simulation
