薄煤保护层综采工作面过地质异常区安全技术研究

Safety measure study of low coal fully mechanized mining face passing through geologic abnormal place

薄煤保护层综采工作面煤层薄,回采过程中经常遇到地质异常区,给生产带来了极大的困难。本文结合实际对5121(0)薄煤保护层工作面过一大面积地质异常区采取三种方案进行分析,提出了较为可行的浅孔预裂爆破松动岩石配合煤机割煤安全技术。

In the thin coal stoping of low coal fully mechanized mining place,it was often caught in geologic abnormal place,and which brought extreme difficulty.In this paper,combined with three kinds of scheme analysis of 5121（0） passing through a large geologic abnormal place,shallow presplitting blasting and coal cutting technique were put forward.
