【摘要】：合理设置采场结构参数是矿山企业需解决的技术难题。以大新锰矿西北采区+340 m中段的采矿工程为背景,采用Mathew图法验核现有采场设计参数的合理性,优化了采场结构参数。研究结果为:1矿山矿柱尺寸选取合理,能够保证开采安全;2矿块斜长为60 m时,Ⅰ矿与Ⅱ、Ⅲ矿的矿房沿走向的极限宽度理论计算值分别为13.5,10.8 m;建议在今后采矿设计中矿房宽度取9 m;3合理布置西北采区Ⅱ、Ⅲ矿矿柱与Ⅰ矿矿房采空区位置,使之达到上下对应,减少矿柱不合理布置带来的安全隐患。
[Abstract]:Reasonable setting of stope structure parameters is a technical problem to be solved by mining enterprises. Based on the mining engineering of the 340m middle section in the northwest mining area of Daxin Manganese Mine, the structural parameters of the stope are optimized by checking the rationality of the existing stope design parameters by using the Mathew diagram method. The results are as follows: (1) reasonable selection of mine pillar size can ensure the safety of mining; (2) when the inclined length of ore block is 60 m, mine 鈪，
