摘要
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。
The mode of operation of the beam depression and plus with the tall support is the monitoring emphasis of the support and surrounding strata system of the fully mechanized mining coal face with large mining height under the condition of up dip mining. The paper advanced the means and approaches for the monitoring of the beam depression and plus angle of the tall support with large mining height, with the field experiences, determined the controlling range and measure of the beam depression and plus angle of the tall support.
