摘　　要：为解决应力集中问题,采用钻屑法、KBD5电磁辐射仪对工作面动力现象进行预测预报,应用应力计及压力枕预测超前工作面监测应力,提出了赵各庄矿3137D1工作面冲击地压预测预警临界指标;同时采用高位抽放及采空区埋管等综合措施对工作面采空区进行瓦斯抽放,达到了回风流对瓦斯控制的目的,实现了深部大倾角复杂条件下工作面的安全回采,为其他矿井深部动压区域复杂条件下安全开采提供了经验和技术支持。In order to solve stress concentration,drilling method and KBD5 electromagnetic radiation instrument were adopted to predict dynamic phenomena of the working face,advanced working face monitoring stress was predicted by stress metering and stress pillow stress,Zhaogezhuang Mine 3137D1 working face ground pressure forecasting warning critical index was put forward,meanwhile,high drainage and goaf pipe laying were adopted to drainage gas in goaf,which achieved the goal of return air controlling gas,realized safe recovery mining under deep large-inclination angle complex geological condition and provided experience and technical support for other mine under the similar condition.
