Abstract: In order to solve the problem of mining coal under shallow-buried gas pipeline in Wuyang Colliery,anti-mining deformation adjusting device-adjustable smooth base pipeline adjustment technology was put forward and specific technical parameters were present. On the basis of specific condition of Wuyang Colliery,pipeline adjustment technology made 925kt coal was mined in 7801 Mining Face. Safe mining coal under large-caliber pipe was realized. Construction of this anti-deformation device was simple and it provided a new approach for mining under pipeline.
