高架顶梁俯仰工况 (抬头或低头 )是仰采条件下大采高综采面支架 -围岩系统监控的重点。本文提出大采高支架顶梁俯仰角的监测方法和手段 ,结合现场实际 ,确定出高架顶梁俯仰角的控制措施和范围。
Elevated overhead beam pitch conditions (head or bow) is the key point for the monitoring and control of the large mining height fully mechanized coal mining face-surrounding rock system under the condition of sublevel mining. In this paper, the methods and means of monitoring the pitching angle of the top mining beam with large mining height are put forward, and the control measures and the range of the overhead pitching angle of the overhead mining beam are determined according to the actual situation in the field.
