摘要
峰局五矿是多年开采的老矿。近些年 ,随着开采深度的不断增加和开采层次的逐渐下移 ,来自底部岩溶高承压水的威胁日趋严重 ,实际生产能力逐年下降。下组煤能否开采是关系到矿井生存与发展的大问题。作者根据多年的研究成果和工作实践 ,就下组煤带压开采的可行性 。
The Fengfeng Five Mine is an old mine. With increasing the depth of mining and lowering the level of mining as well as facing the more seriously dangerous resulted from the higher karst water pressure in the coal floor, the real productive capacity has annually decreased in recent years. It is a big problem about the living and development of the mine whether the lower series coal can be exploited or not. In the light of some scientific researches and productive practices for years, in the paper authors try to demonstrate some opinions and suggestions about the feasibility of mining the lower series coal with water pressure.
