Abstract:

Based on the characteristics of abnormal strata behaviours of 42103 first fully mechanized caving face during the initial mining period in Bu'ertai Coal Mine, this paper analyses the causes of abnormal pressure and sums up some comprehensive measures of controlling pressure anomalies, including lowering the top coal release speed, using the pump regulator, improving rated working resistance of stents and ensuring reasonable working-bit mode, etc., which have achieved good results.

Key words: Fully Mechanized Caving Face, Mine Strata Pressure, Abnormal Strata Behaviors, Control Measures
