本文以泊江海子矿侏罗系首采煤层3-1煤为研究对象,运用岩石力学和工程地质等学科理论和方法,从顶板的沉积相、岩性、岩性组合和构造等方面入手系统研究了首采煤层的工程地质特性,分析了影响煤层顶板稳定性的因素。重点阐述了煤层顶板工程地质特性,指出了煤矿开采过程中可能发生的工程地质问题,对区内可能发生的不良地质现象提出了治理建议。
This paper takes the first coal seam of coal seam Jurassic in Haizi, Pojiang, as the research object. By using the theories and methods of rock mechanics and engineering geology, it starts from the sedimentary facies, lithology, lithology combination and structure of the roof The engineering geological characteristics of the first coal seam are systematically studied and the factors affecting the stability of the coal seam roof are analyzed. The engineering geological characteristics of coal seam roof are expounded emphatically. The engineering geological problems that may occur in the process of coal mining are pointed out, and some suggestions on treatment of adverse geologic phenomena in the area are proposed.
