赵坡煤矿条带开采方案研究

赵坡煤矿村庄压煤量占矿井可采储量较大,为了矿井的生产和长远计划,在对地面房屋不产生影响或产生轻微影响情况下对压煤进行开采。根据区域地质开采条件及地表沉陷基本规律,分析了地表移动变形的基本特征,确定了研究区域12下、14、16、17四个煤层开采的地表移动变形合理计算参数,并进一步分析了村庄下压煤开采的基本途径,确定了村下开采方案和技术措施。通过运用数值模拟分析和开采方案综合分析,设计12下、14、16、17四个煤层条带法开采工作面的合理开采宽度。

Study on Zhaopo Mine Band Mining Project

Coal under the village in Zhaopo Mine was large, considering mine production and long-term planning, the mining plan without or little influence on ground houses was settled. According to the regional geological mining eonditions and the basic rules of surface subsidence, the basic characteristics of surface movement deformation was analyzed, the 4 coal seam 12 r, 14, 16, 17 reasonably surface movement deformation parameters were studied, and coal under the village mining basic approach was analyzed, the mining plan and technical measures were settled. By using numerical simulation analysis and comprehensive analysis of mining method, 4 coal seam 12 下, 14, 16, 17 band mining project reasonable working face mining width were designed.
