摘 要:在清水江矿既有采矿方法基础上,利用充填法对保安矿柱进行置换,先回采保安矿柱,再进行充填,完成保安矿柱置换,然后再大面积进行矿体回采,并根据地质报告及现场岩石力学参数对清水江矿矿房宽度进行了计算,考虑了岩石的弯曲、剪切等一系列力学条件,对开阳县及周边矿区矿柱置换具有借鉴意义。Based on the existing mining method in the Qingshui River mine,its security pillars are replaced.The filling method is used to replace security pillars.Security pillars are first mined and then are filled to complete their replacement,and then a large area of the mine body is mined.According to the geological report and the mechanical parameters of on-site rock,the mine room width of the Qingshui River mine is calculated,and a series of mechanical conditions such as the bending and shear of rock are considered,which has reference significance for the replacement of mine pillars in Kaiyang County and its neighbouring mine areas.
