摘要
针对新阳能源公司属于黄河北煤田薄煤层的特点,在薄煤层砂岩顶板沿空留巷工艺的基础上,对支护参数进行深度优化,并进行现场应用,优化后有效解决了原留巷工艺一系列的问题。本文根据4702工作面的地质条件并结合工程实际,对其进行可行性研究。
In view of the fact that Xinyang Energy Company belongs to Huanghebei coalfield,characteristic of thin coal seam in the thin sandstone of coal seam roof,on the basis of which,the supporting parameters is optimized,and applied,effectively solving the series of problems of the original process.Based on the geological conditions of 4702 and the engineering practice,the feasibility study is carried out in the paper.
