Gas in working faces is mainly produced in the destressing and desorption process of the coal bed,The coal beds are too soft to carry out bedding drilling and draw gas effectively.Mining in coal beds with gas of high conentration and low permeability and gas suction can be operatodDuring mining activities in the working faces,gas released from roof fracture areas will not flow intoupper corners, so the technically drilling problem in soft coal beds with low permeability and high
