基于某典型矿区三软煤层开采软弱煤岩体不易加工成型、不规则试样的力学性质测试的问题,采用新型的YDS-2型携带式岩、土力学性质多功能试验仪,测试加工的混凝土包裹煤岩体试块,分析得出了软弱煤岩样物理力学参数,为研究三软煤层采场及回采巷道围岩的稳定性控制设计提供基础的依据。
Based on the problem that the soft coal and rock mass are not easy to be processed and the mechanical properties of the irregular samples are tested in the mining of three soft coal seams in a typical mining area, a new type YDS-2 portable rock and soil mechanics multifunctional tester is used to test and process the concrete The test blocks of coal and rock mass were wrapped to analyze the physical and mechanical parameters of soft coal and rock samples, which provided the basis for studying the stability control design of the stope and the roadway surrounding the mining seam in soft coal seam.
