兴安煤矿属高突矿井,由于煤层赋存瓦斯压力较大,给通风安全瓦斯管理带来极大隐患。开采保护层是治理瓦斯隐患的一种手段。结合兴安煤矿的具体情况,通过保护层开采措施的制定和验证,对27、24层进行了保护层开采,并对对23层煤的保护效果进行了分析,认为该技术作为一种治理瓦斯隐患的手段,近年来也越来越多地被利用,取得了很好的效果。
興安煤礦屬高突礦井,由于煤層賦存瓦斯壓力較大,給通風安全瓦斯管理帶來極大隱患。開採保護層是治理瓦斯隱患的一種手段。結閤興安煤礦的具體情況,通過保護層開採措施的製定和驗證,對27、24層進行瞭保護層開採,併對對23層煤的保護效果進行瞭分析,認為該技術作為一種治理瓦斯隱患的手段,近年來也越來越多地被利用,取得瞭很好的效果。

Xingan Colliery belongs to high outburst colliery with high pressure of gas occurrence in seam, which brings great hidden danger for gas management of ventilation safety. The paper has introduced a method of con trolling gas by mining under protective layer. Combined with the actual conditions of Xingan Colliery, protective layer mining was carried out on 27th and 24th layer by determining and verifying the measures of protective layer mining, and protection effect of 23 th layer was also analyzed. As a method of treating gas hidden danger, this technology has been used increasingly in recently years, which has obtained good effect and can be widely applied in all over the country.
