摘要
在大角度俯采条件下,以23123轻放工作面为例,对回采过程中存在的问题进行分析,并提出解决办法,成功实现了轻放工作面的大角度俯采,并为类似地质条件的煤层开采提供了借鉴经验。
Taking the No.23123 working face as an example, the problem in the coal mining of large - angle underhand stoping is analyzed. The method is pointed out. The mining of fully mechanized caving face in the large- angle construction is realized. The experience and reference are provided for the coal seam mining of the similar geolegic condition.
