    • Abstract
  • To pass a "single square" danger zone of full-mechanized caving face, achieve effective control of governing hard roof rock burst, by optimizing the design of preventing rock burst of “single square” hard roof, the support pressure monitoring, micro-seismic monitoring, numerical simulation and in-situ observation, evaluation methods are used to carry out real-time monitoring, recording, statistics and analysis of rock pressure before and after fully-mechanized caving face passing through “single square” hard roof. The results show that hard roof strata can release energy and roadway deformation is large with good caving characteristic in “single square” area, which is very good solution to the hard roof rock burst.
