JIA Liang-liang
Abstract：Based on spatial relations and uses of the North East air return way and 21007 transport connection lane in Chensilou Coal Mine, combining with the existing transport system, the paper proposed the roof air bridge which had little influence on the original production system, less engineering quantity, convenient construction, and realized water self-flowing. By controlling the key links, including roadway reinforcement, equipment layout, blasting, airflow control, face protective walls, concrete block and so on, safe, fast and efficient construction of air bridge was ensured.
