综合机械化采煤工艺的产生和发展,促使传统的采区巷道布置发生了变化和改革。我国大同、开滦、阳泉、徐州、枣庄、兖州、鸡西、邢台、淮北、松藻等矿区,在相应条件下采用倾斜长壁采煤法就是一例。本文依据我国近年来十余个倾斜长壁综机采面矿压实测资料,阐明倾斜长壁采面矿压规律,为液压支架选型及控制好顶板提出几点建议。
The emergence and development of mechanized coal mining process has led to the change and reform of the traditional roadway layout in mining areas. China’s Datong, Kailuan, Yangquan, Xuzhou, Zaozhuang, Yanzhou, Jixi, Xingtai, Huaibei, Songzao and other mining areas, under the appropriate conditions using inclined longwall mining method is an example. In this paper, based on the measured data of over ten inclined longwall mechanized coal mining face in recent years in our country, the regularity of rock pressure in inclined longwall face is expounded, and some suggestions are put forward for selecting and controlling the hydraulic support.
