综采放顶煤工作面提升资源回收率分析

Analysis on the Improvement in the Recovery Rate of Resources at the Fully Mechanized Top Coal Caving Face

综采放顶煤技术已成为厚煤层及特厚煤层开采的关键技术,虽然其很大程度上提高了煤层开采的效率,但是在开采时存在着资源回收率低的问题。为了提高综采放顶煤资源的回收率,减少煤炭资源的浪费,通过分析造成综采工作面资源回收率低的原因,提出了一些改善综采放顶煤资源回收率的措施。

The technology of fully mechanized top coal caving has become the key technology for thick and super thick coal seam mining. Although it has largely improved the efficiency of the coal seam mining, there also exists the problem of low recovery rate of resources in mining. In order to improve the recovery rate of resources at the fully mechanized top coal caving face and reduce the waste of coal resources, the paper analyzed the causes of low resource recovery rate at the fully mechanized top coal caving face and put forward some measures to improve the recovery of resources at the fully mechanized top coal caving face.
