结合某矿山实际需求,对充填体强度进行试验研究,探究灰砂比,浓度,以及外界条件围压对充填体强度的影响试验结果表明,充填体强度随着灰砂比和浓度的增大而增大,特别是在施加围压后,充填体强度显著提高,灰砂比1∶8时1 MPa围压下的三轴抗压强度是单轴抗压强度的1.95倍。实验结果对矿山充填工作参数的选择具有指导意义。 According to the actual demand of a mine, the strength of the filling body is studied and studied. The effects of the sand ratio, the concentration and the confining pressure of the external conditions on the strength of the filling body are tested. The results show that the strength of the filling body increases with the increase of the ratio of sand to sand Increase, especially in the confining pressure, significantly increased the strength of the filling body, sand and sand ratio of 1: 8 1 MPa confining pressure under triaxial compression strength is 1.95 times the uniaxial compressive strength. The experimental results have guiding significance for the selection of mine filling parameters.
