摘要
开滦矿业集团赵各庄矿的开采深度达1 000 m,煤层倾角达36,°大采深和大倾角的共同影响下,工作面表现出复杂的矿压显现规律。采用现场观测了工作面顺槽变形和工作面支架受力,采用数值模拟对大采深、大倾角综采的矿压显现规律进行模拟研究,得出了了一些初步的结论。经过工业性试验,认为在采取一定的措施后,大采深、大倾角条件下的煤层综采完全可行,可以取得较好的技术经济效益。
The mining depth of KaiIuan is up to 1 000 m and inclined angel is up to 36°. Due to the effect of it, the strata behavior of working face is complex. The distortion of entries and support pressure are observed in situo The strata behavior complexity in large mining depth and high inclined seam is studied with numerical simulation. By commercial-scale trial, it is feasible that fully-mechanized mining in large mining depth and high inclined seam, and the better technical-economic efficiency could be acquired.
