    Fire Control Technology of Spontaneous Combustion at Fully Mechanized Caving Face Under Complex Conditions

    • Due to the effect of coalfield fire zone in Xinjiang Fukang Coal Mining Area of Northern Piedmont of Tianshan Mountains, in the late mining period of Dahuangshan Coal Mine + 735 middle and large slot fully mechanized caving face, overlying rock connected with the treated coalfield fire zone after the large scale of caving, which leads to residual coal spontaneous combustion in original warehouse goaf and affects working face. On the premise of scientifically determining spontaneous combustion fire location, after the comprehensive technical measures of orderly implementation of "drilling filling colloid, thickening sludge isolation block, injecting nitrogen inerting and unsealed lock wind piece by piece, pre-inhibiting float coal in overlying warehouse goaf and low volume air supply", spontaneous combustion disasters are controlled safely and effectively, which ensures the safety mining.
