山东鲁西诸煤田中普遍存在以石炭二叠纪煤系和奥陶系之间的假整合面为主滑面以及煤系中若干次级滑面共同组成的多级重力滑动构造体系,煤系中滑动构造现象十分常见,其与煤层底板突水、煤层自燃、煤和瓦斯突出、冒顶事故等矿井灾害之间存在着密切的联系。本文阐述了鲁西煤田滑动构造发育的基本特征及其与各种矿井灾害之间的关系,并对如何改善生产条件、搞好安全生产等方面进行了初步探讨。
In Shandong Luxi coalfields, there are common multi-stage gravitational-sliding structural systems composed mainly of fake integrative surfaces between Carboniferous Permian coal measures and Ordovician series and several secondary slip surfaces in coal series. Coal measures It is very common in middle slip structure. It has close relationship with mine disasters such as water inrush from coal seam floor, spontaneous combustion of coal seam, coal and gas outburst and roof fall accident. This paper expounds the basic characteristics of sliding structure development in Luxi coalfield and its relationship with various mine disasters, and discusses how to improve production conditions and improve safety production.
