充填综采技术是一项新型的采煤技术。利用采空区充填技术,一方面可以解决“三下”呆滞煤难采,煤炭资源采出率低的问题;另一方面可以有效利用煤矸石实施充填,减少废弃物排放,实现经济、环保双效益。文章基于岩层控制的关键层理论,采用FLAC数值模拟软件,对采空区充填前后岩层应力、应变规律进行了分析,从而为制定合理的充填方案提供一定的研究基础。
Filling mechanized mining technology is a new type of mining technology. The use of worked - out area backfilling technology, we can solve the problems that "three down" coal is hard to mine and the rate of mining out is so little. On the other hand, we can backfill the work - out area with coal gangue reduing waste emissions and realizing the double benefit of econmic and enwironment. Based on a critical layer of strata control theory, the page analyzed the rock stress and strain of the work - out area using the FLAC numerical simulation software. So it can provide some basic content for a reasonable filling program.
