摘要
以某铜矿为例 ,在简介其无间柱连续采矿法的基础上 ,建立了该矿 1分区充填体的三维楔体模型 ,重点计算岩墙对充填体的侧压力和考虑爆破地震对 1分区充填体稳定性的影响 ;然后建立充填体的极限状态方程 ,求出了在试验矿山地质采矿条件下 ,1分区充填体的安全系数和可靠指标 ;与现有文献的结果进行比较 ,证明建立的模型和方程更具实用性。
Taking a certain copper mine as an example, the authors describes briefly non pillar continuous mining methods, and on this basis present a three dimensional wedge mathematical model for backfilling of the mine′s No.1 mining area to calculate side pressure of rock wall on backfilling and predict the influence of blasting seismic on the stability of No.1 mining area′s backfilling. A limit state equation is established for the backfilling, and this equation is used to solve for the safty coefficient and reliability of No.1 mining area′s backfilling. Compared with the results reported in literatures, the model and aquation are found to have practicability.
