摘要
乌兰煤矿主采煤层多,煤层瓦斯含量大,且多个主采煤层都是突出煤层。通过对8#煤层5867综采面进行沿空留巷方案技术研究和方案实施,取得了留巷成功,为乌兰煤矿开采技术进一步积累了成功经验。
Coal seams of Wulan coal mine are rich of gas, and several main mining coal seams are outburst coal seam. Successful experience was got through researching on gob-side entry retaining technology of 5867 fully mechanized face.
