回采工作面采空区开放式漏风治理技术

Control Techniques of Open Air Leakage in Stope Face Goaf

离柳焦煤集团丈八井9#煤层大部分已被小煤窑滥挖乱采破坏,造成工作面漏风非常严重,携带大量有害气体的漏风窜入工作面,严重威胁工人的生命安全。通过分析工作面采空区漏风特点,提出老空区有害气体的探测、工作面开区均压等技术措施,并辅以及时可靠的有害气体检测等管理手段,有效解决了工作面有害气体超标问题。

Most parts of the No.9 coal seam in Zhangba Well of Liliu coking coal group,had been destroyed by small coal mines indiscriminately mining,which caused very serious air leakage in the face and carried large amounts of harmful gases to the face,it was a serious threat to the safety of workers.By analyzing air leakage characteristics in the goaf,the measures of hazardous gas detection technology in old mining area and face pressure equalizing technical had been proposed.Supplemented by timely and reliable management of hazardous gas detection means,this effectively solves the issue of harmful gases overrun in the working face.
