灵北矿井防治大巷底鼓支护技术研究

Study on Support Technology of Floor Heave Prevention in Lingbei Coal Mine

灵北矿井井底车场集中轨道大巷大部分区域出现顶部、帮部开裂,该巷道所施工完毕的水沟均已开裂或挤压变形。本文探寻铝土泥岩巷道底鼓治理技术,为该矿及汾西矿区乃至全国类似巷道的支护提供参考。

Roof and wall cracking occurred at the most area of centralized orbit tunnel in shaft station, Lingbei Coal Mine, all built water ditch in roadway cracked or extruded. The paper probed into treatment technology of floor heave of bauxitic mudstone, which provided reference for roadway support in this mine, Fengxi Mining Area and even similar roadway in the whole country.
