摘要
采用理论分析、数值模拟与现场实测方法分析了五阳煤矿7522大倾角俯采综放工作面矿压显现特征,对大倾角俯采工作面设备防滑配置、采煤工艺选择、设备稳定性控制、顶板控制技术、安全技术措施、工作面排水设计等关键技术进行了研究,介绍了具体实施措施。通过现场实践应用,取得了较好的技术经济效益。
Using theorial analysis, numerical simulation and field measurement method, the characteristics of strata behaviors in 7522 underhand full-mechanized caving face with large dip angle in Wuyang Coal Mine were analyzed, and the key technical problems such as antiskid configuration, mining method selection, equipment stability control, roof control technology, safety technology measures and drainage design in working face were studied, then the concrete imple-mentation measures oF above problems were introduced. By field application, it had achieved good technical and economic benefits.
