摘要:

稳定的采场是金属矿山深部安全开采的关键。针对云南某矿的工程地质条件和矿体赋存特征,采用Mathew法对采场极限暴露面积进行理论计算,得到采场长度为30 m和40 m时,采场极限暴露面积分别为600 m2和684 m2,运用2种数值建模法对理论计算结果进行模拟验证,模拟结果表明采场极限暴露面积介于600~700 m2之间。研究结果表明,结合理论计算和数值模拟方法,能够在保障矿山安全开采的情况下合理确定最优采场结构参数。对2种数值建模模拟法进行对比可知,与常规建模数值模拟法相比,简化建模数值模拟法表现出明显的优势。

关键词: Mathew法, 数值模拟, 稳定性分析, 极限暴露面积

Abstract:

 The steady stope is security assurance of mining in deep metal mines.Due to engineering geological conditions of a mine in Yunnan as well as occurrence characteristics of orebody,the maximum exposed area was calculated by Mathew method,and the maximum exposed area obtained with Mathew stability diagram method was 600 m2 and 684 m2,respectively,as the stopes long were 30 m and 40 m.The simulation verification was used by two methods of numerical simulation,both the maximum exposed area obtained with two numerical simulation  were between 600~700 m2.Research results illustrate that data obtained with those two methods can meet mining security requirement in stope.By comparing two kinds of numerical modeling simulation method,meanwhile,the simplified modeling numerical simulation method is superior to the conventional modeling numerical simulation method.

Key words: Mathew method, numerical simulation, stability analysis, limit exposed area
