Research on Fire Prevention and Extinguishment of Working Face by Fully Mechanized Sub-Level Caving Mining of Shallow Inflammable Thick Coal Seam
摘要
Abstract
Aimed at the problems of coal spontaneous combustion of working face by fully mechanized sub-level caving mining in shallow inflammable thick coal seam, the conditions of the shallow depth based on the fire prevention was proposed, the characteristics of the inflammable outcrop and the large space, the more residual coal, the serious air leakage and other other aspects of the fully mechanized top coal caving for the shallow thick coal seam have been studied, a new mining method adapted to the outcrop mining or open-cutting extension to underground mining was introduced, the positive pressure ventilation , the backfills in buries and the roller compaction were expounded, the spontaneous combustion hazard zone in the goaf was determined, the comprehensive technology of fire prevention and extinguishment was conducted mainly with injection of nitrogen in the goaf and secondarily stifling by water or grouting. This prevented coal spontaneous combustion and protected the safety of the mine rescue team members. After several successful engineering practices, research have been adopted in Hai-bowan mining area, showing great theoretical and practical values to similar conditions in mining method and safety production.关键词
