On the exploitation of the high spontaneous combustion of thick coal seam gas control of the NO.1 mine in Yangquan

High-thick coal seam gas pilot to promote top-coal caving face "a built-end alley" and "high-pumping Lane" positive drainage way, complemented by practical forecasting the risk of spontaneous combustion technology, the use of both pressure ventilation to control air leakage, shotcreting plugging, drilling grouting techniques effectively prevent the mining of thick coal seam to spontaneous combustion smoke-free.
