摘要
井工开采地质条件复杂,工作面设计多为不规则工作面。通过对传统回采工艺的改进和创新,保证了持续生产,提高了工作面回采率。简述回采工艺共性技术与关键技术的对比,分析旋转停采工艺的可取之处及改进方向。
The geological conditions of well mining are complicated,and the design of working face is mostly irregular working face.Through the improvement and innovation of the traditional mining process,continuous production is guaranteed and the mining face recovery rate is increased.Briefly describe the comparison between the common technology and the key technology of the stoping process,and analyze the desirability and improvement direction of the rotating stop process.
