Abstract: When the working face is passing the square position, the overlying rock strata will change drastically, which is easy to cause a series of rock pressure problems such as rock burst. Based on the monitoring data of microseismic, mine pressure, stress, CT, etc., the monitoring results in the square phase of the working face are researched and summarized. The research results show that in 307 working face, the number of microseismic events and the number of energy increased significantly in 3-6 days before the square; the resistance of incoming pressure and the resistance of non-compression work during the square period are greater than those during the non-square period, and the rock pressure data is close to the working surface significant increase occurs when the square position; the leading support stress will also increase before the square, and its value is greater than the impact of general mining; the risk index of rock burst near the square also increased significantly; approaching to the square position, the stress monitoring, microseismic monitoring and mine pressure monitoring data will successively increase to different degrees and last for a period of time. Microseismic, rock pressure, stress and CT can be used as monitoring and early warning indicators of 307 working face to guide the work of working face pressure relief, and a monitoring and early warning system including “force- vibration-energy” is proposed.
