摘要:在煤矿保护层开采技术中,保护层如果留设有煤柱将会对被保护煤层突出危险性的消
10 除造成严重的影响。本文以红菱煤矿西三采区保护层开采为背景,通过对比被保护层受保护层煤柱影响范围内外的不同区域的***突出危险性,总结得出了煤柱留设对被保护煤层突出危险性的影响。结果表明在煤柱影响区内,被保护煤层的突出危险性依然存在,需要采取相应的补充措施。这为矿井的安全生产提供了数据基础和参照依据。

Abstract: In protective layer mining technology, the outburst risk elimination in protected
25 layer will be seriously affected by the coal pillar existed in protective layer.
In this paper we take protective layer mining project in Hongling Coalmine as backgroud, compared the outburst risk in and out of the area which affected by the coal pillar exsited in preoctective layer. The results show that in the coal pillar affected area the outburst risk still exist. plement measures are needed to eliminate the risk. That provide the data base and
30 reference to the safety in production.
