摘要
Abstract
The overlying 12 coal mined-out area exists about 553 m room mining area along 22307 face of Bulianta Coal Mine,the geological structure of shallow buried coal seam leads to room mining area with plenty of water,using oil bath temperature programmed experiment,through the contrast analysis of oxygen consumption rate under the condition of different moisture content in the process of oxidation heating process,we obtain that oxidation reaction of residual coal is faster after soaking and discharging water,and spontaneous combustion risk is bigger.Taking advantage of the original agent plug-hole to inject nitrogen and inert overlying 12 coal room mining area during draining water,constructing ground drilling to carry out preventive grouting of overlying room mined-out area ensures the safety mining of 22307 face.关键词
