Abstract
Huangling Mining Area belongs to the coal oil and gas symbiosis mining area. In the process of coal mining, it is threatened by coal seam gas and surrounding rock oil type gas. The gas control in the mining area has gone through the stages of pure ventilation, mobile pump extraction, fixed pumping station extraction and so on, from the aspects of imitation study, analysis and summary, laboratory construction and so on, the technical management system of "precise gas extraction", which includes detailed description of gas geological conditions, accurate design, accurate construction, standard extraction and post-evaluation guarantee, has been developed gradually. Gas treatment in mining area enters from "to cure" to "to be accurate and save cost", the mine in the area has realized gas"zero" over-limit and safety"zero" purpose for many years.关键词
