| 摘 要： | 不稳定煤层的开采有着诸多的技术难题。根据广西呼略矿不稳定煤层倾斜长壁开采的工业性试验,以及矿压观测成果,得出了工作面的矿压显现规律,分析了由直接顶周期性断裂而引起采场的周期来压现象,阐述了沿空成巷的力学原理,提出了在这种开采条件下岩层控制的技术措施。经过几年的生产实践,该矿取得了高产、高效、坑耗低、安全好的明显效益。图4,表1,参8。

| Abstract: | There are many technical difficulties in mining unstable seam. Based on the industrial mining test of the unstable coal seam and the results of ground pressure observations in Hulue mine.it obtained the rule of strata behaviors of the working face, and analyzed the periodical pressure arose from periodical break occurred in nether roof, and explained mechanical principle of the road retained for next sublevel, the technical measures of strata control under this condition are put forward . By production practice for several years, it achieved evident benefit of high output, high efficiency, low timber consume and well safety in this mine. 4figs. ,1tab. , 8refs. |
