The Measurement of Underground Pressure Regulation in Ulan Moron Coal Mine

Based on theoretical research as well as in situ tests, this paper reveals behavior features of mining pressure appearance and the performance of supports for fully mechanized long wall face in Ulan Moron Mine. Depending on systematic analysis of features of working face mine pressure from field tests data, the regular pattern of mine pressure is listed into three stages, which are first weighting, fault-crossing, and end of panel.
