Gas in working faces is mainly produced in the destressing and desorption process of the coal bed, gobs and adjacent strata. The coal beds are too soft to carry out bedding drilling and draw gas effectively. If gob gas suction is adopted in a large area,the project will prove not only extremely difficult,but also fail to draw out gas of high concentration. Therefore, efficient gas suction is technically determined by seeking fracture aisles for gas movement and gas zone of enrichment. In the course of mining and destressing, gas originating from large destressing areas will go through the fracture aisles of the full development areas and gather in annular fracture areas. The similar material experiments in the laboratory, the numerical simulation and the in-situ study are applied in this work in order to find the location of annular fracture areas in overlying formation. The long-drill mehtod for gas suction along the strike of annular fracture areas is adopted. Mining in coal beds with gas of high conentration and low permeability and gas suction can be operatod separately. During mining activities in the working faces,gas released from roof fracture areas will not flow into upper corners, so the technically drilling problem in soft coal beds with low permeability and high concentration gas can be solved. The application of this technology in the working faces of the gassy mines in Huainan shows that gas suction rate is above 60 percent, making it possible to mine safely,efficiently and intensively.
