Prevention and Control Technology of Coal Spontaneous Combustion at Fully Mechanized Caving Face of Steep - inclined and Extra - thick Coal Seam
Abstract：Aiming at the spontaneous combustion condition in the gob of the 5521 - 15 mining face, the key factor of spontaneous com- bustion occurred in the gob was discussed. The comprehensive control measures of coal spontaneous combustion were put forward by using primarily big flow perfusion three - phase foam to cover widely float coal, taking complementally pressure balancing plugging and acceleration of working speed, which effectively controlled the spontaneous combustion of 5521 -15 fully mechanized caving face and ensured the safety mining.
