合理选择采煤方法和采煤工艺是实现急倾斜薄及极薄煤层安全、高效、低耗开采的根本途径。根据双鸭山市近距离、急倾斜薄煤层,多煤层同时开采的特点,认为以往仓储式采煤法、走向长壁采煤法、台阶式采煤法、巷道式采煤法等,存在通风系统不合理、回采效率低、安全管理难度大等问题。经探索和研究认为,走向长壁分带采煤法在技术、安全和经济等方面均有较强应用和推广价值。
Reasonable choice of coal mining methods and coal mining technology is to achieve steep thin and extremely thin seam safety, high efficiency, low-cost exploitation of the fundamental way. According to the characteristics of Shuangyashan city’s close and steep inclined thin coal seams and multiple coal seams at the same time, it is considered that the conventional storage-type coal mining method, the long-wall mining method, the step coal mining method, the tunnel coal mining method, etc., Reasonable, inefficient mining, safety management and other issues. After exploration and research, it is believed that the move to longwall zone mining has strong application and promotion value in technology, safety and economy.
