| 摘 要： | 针对京煤集团木城涧矿，大台井地质条件与煤的赋存状况，通过相似模拟实验方法，讨论急倾斜煤层开采解放层的可行性。通过观测煤岩失效过程，了解冲击地压的发生规律，裂隙带发生、发展过程和解放范围，为安全回采提供科学依据。通过研究先回采11槽煤对12槽煤的解放效果，为后续的局部反程序开采作为防治冲击地压的一项措施奠定理论基础。

| Abstract: | As to the geologic and the burring situations of coal seams in Muchengjian mine in western Beijing, the possibility of extracting protective seam is discussed in dip-slopping coal seams through physical modeling experiment. The rule of rock-burst, the generation and development of crack band, and the range of liberation are studied through observing the process of failure. The results of experiment provide a scientific basis for safe mining production. The #11 coal seam is extracted and the #12 coal seam is liberated. The liberation can prevent the rock-burst in the consequent extraction. The result of experiment found the theoretical base for prevention in the rockburst. |
