一、问题的提出兴隆庄煤矿自1992年使用综采放顶煤技术开采以来,已经历15个年头,在这段时间内,综采放顶煤技术得到了迅猛的发展,工作面单产和效率大大提高,取得了良好的技术经济效果。综采放顶煤成为厚煤层开采的主要技术。但目前,有些矿井对顶煤放出规律及合理的放
First, the issue put forward Xinglongzhuang coal mine in 1992 since the use of fully mechanized mining technology has been through 15 years, during this time, fully mechanized top caving technology has been the rapid development of face production and efficiency Greatly improved and achieved good technical and economic results. Fully mechanized top coal caving has become the main technology of thick seam mining. However, at present, some mines release the law of top coal and put it rationally
