摘 要:为掌握融冠矿业矿山开采至深部时对斜坡道及地表的影响,开展相应的岩石力学研究工作,对主要揭露的石榴石矽卡岩、绿帘石矽卡岩、凝灰岩及矿岩进行室内力学实验并通过RQD和BQ分级法进行岩体稳定性评价。结果表明:四种岩性的单轴抗压强度分别为118.96 MPa、113.34 MPa、137.29 MPa、158.00 MPa,抗拉强度为14.96 MPa、16.31 MPa、21.45 MPa、31.91 MPa;利用RQD和BQ评价法对石榴石矽卡岩、绿帘石矽卡岩、矿岩及凝灰岩进行岩体质量分级及评价,其岩体质量为Ⅱ~Ⅲ级。In order to grasp the influence of the Rongguan Mining mine on the ramp and surface when mining to the depth,the corresponding rock mechanics research work was carried out,and the indoor mechanical experiment and rock stability evaluation by RQD and BQ grading method were carried out on the main exposed garnet skarn,green cordite skarn,tuff and ore rock.The results show that the uniaxial compressive strengths of the four lithologies are 118.96 MPa,113.34 MPa,137.29 MPa,158.00 MPa,and the tensile strengths are 14.96 MPa,16.31 MPa,21.45 MPa,31.91 MPa,respectively;the rock quality grading and evaluation of the garnet skarn,the green cordite skarn,the ore rock and the tuff were carried out by utilizing the RQD and BQ evaluation methods.The rock quality was graded and evaluated using RQD and BQ evaluation methods,and its rock quality was classⅡ~Ⅲ.
