大倾角薄煤层走向分带采煤方法应用与实践

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。

Application and Practice of Strike and Zoning Mining Methods in Inclined Thin Seam

Selecting the rational coal mining mehod and trchnology is a fundamental way to achieve safe,high efficient and low mining.According to the characteristics of close range,steep thin coal seam,and multi-seam mining at the same time in Shuangyashan City,some problems exist in the wavehouse mining,strike longwall mining,step-mining and roadway mining,such as the unreasonable ventilation system,low mining efficiency and large difficulty of safe management etc.After exploration and research,it is believed that t...
