综放工作面旋转回采工艺的研究与实践

The Study and Practice of the Method for the Mining of a Fully-mechanized Top-coal Caving Face after Turning Round

提出两种综放工作面旋转回采方法,经对比,选择了短刀截割回采方法。介绍了该方法的回采工艺及开采过程中遇到问题的处理,以及应用此方法获得的显著经济效益。

Two methods are proposed for mining such a face. Based on result of comparison the narrow-wed cutting method is adopted. A description is made in the paper of the selected coal cutting process and the approach for tackling the problems arising in the course of coal cutting. The application of such a mining process has met remarkable economic result
