摘要
合理的矿体回采顺序,是保证矿山高效安全生产的重要环节。结合铜山铜矿的采矿方法和矿体赋存特征,采用FLAC3D数值模拟软件,建立了三维数值计算模型,根据岩石力学试验结果和现场地应力实测资料施加合理的初始条件,对铜山铜矿30#矿体的回采顺序进行模拟研究,从应力、位移等方面对不同回采方案进行分析比较,从而得出较优的开采顺序方案,可为类似矿山安全生产提供重要参考。
Rational mining sequence is an important factor to ensure the efficient and safe production of the mine.Combining with the mining method and ore body characteristics of Tongshan copper mine,a 3D dimensional computational model was established with FLAC3 D numerical simulation software.According to the experimental results field data and rational initial conditions,the mining sequence was simulated for No.30 ore body.Different mining schemes were analyzed and compared from stress and displacement,so as to obtain the optimal mining scheme,which was of important reference to the safe production.
