摘要
在复杂地质条件下,要保证回采安全,必须制订安全可靠的技术措施。枣园煤矿结合自身经验,采取逐步起架、防片帮、防顶板垮落、加强注水的方法,在采面仰采期间倾角大于25°情况下,有效保证了采面安全回采及工程质量。
In the complicated geological conditions, it should make the safe and reliable technique measures to ensure the safe mining. Combined with its experiences,the methods of hoisting supports gradually, preventing rib spalling, preventing roof fall, strengthening the water injection,were adopted in Zaoyuan Coal Mine. By these awys, the safe coal wining and the quanlity of engineering were ensured while the angle of overhand mining face is greater than 25°.
