摘要
分析了造成综合机械化放顶煤存在回采率低的主要原因,针对这些原因结合工作面布置、推进距离并结合支架选型及工艺参数的优化,提出改善放顶煤回采率低的相应措施,对于提高综放工作面采出率具有一定的意义。
The paper analyzes the main reasons of low recovery ratio in the fully-mechanized top-coal mining. Then, the working face distribution, advance distance, support selection and technique parameters are optimized; corresponding measures are provided. All are important to increase the recovery ratio.
