Practices on Fire Prevention and Control During Initial Mining Period of No. 3301 Fully Mechanized Top Coal Caving Mining Face in Yangcheng Mine
Abstract：In order to prevent and control the coal spontaneous combustion in the goal caused by the slow advancing speed, coal left in the goaf, serious ventilation leakage and others during the initial mining period of No. 3301 fully mechanized top coal caving mining face in Yangcheng Mine, in combination with the mine actual conditions, the comprehensive control measures to speed up the coal mining face advancing speed, to adjust ventilation value, to reduce the ventilation leakage, to inject glues, to inject inert gas and to spray the inhibitor were provided. The results showed that after the comprehensive control measures applied, the CO volume fraction in the air returning flow of No. 3301 fully mechanized top coal caving mining face was reduced from 501.25×10-6 to 17×10-6. Thus a safety mining during the ini- tial mining period could be ensured.
