摘要
介绍了中国煤矿工程机械装备集团公司的三套综采成套设备在印度的使用情况 ,分析了地面未爆破期间综采工作面矿压特点 ,探讨了浅埋深难垮顶板煤层地面爆破方案及实施情况。结果表明 ,使用该方法可以很好地控制浅埋深难垮顶板。
This paper introduces the working situation of top coal caving equipment in India, which was exported from China. The ground pressure of top-coal caving face by surface blasting with both shallow buried seams and poor main roof is analyzed, the blasting methods and working situations are also described. The results show that the methods mentioned in this paper could be adopted to control the roof strata properly in certain case.
