Study on Technical System of Coal and Gas Outburst Prevention and Control in Guizhou Coal Mines
摘要
Abstract
There are some problems in technical system of controlling coal and gas outburst in Guizhou coal mines because the coal seam occurrence condition is complex and the type of coal mine is small scale.The problems that it is difficult to select the protective layer of the coal seams all of which have outburst risk,the position of special gas drainage lane is not scientific,the sensitivity of the forecast indexes and the equipment should be equipped are studied in this paper.Using the constructed coal seam outburst risk level evaluation model,we sorted out the outburst risk of typical coal-bearing structural units in Guizhou province,and recommend the reasonable protection layer by the constructed protective layer selection method.The principle of layer layout of gas drainage lane in Guizhou outburst mines is established,and the reasonable layer of typical coal bearing structure unit is recommended.The sensitive index of coal mine in Anshun,southwestern Guizhou and Liupanshui area is K1,and Zunyi and Bijie area is △h2.Soft layer index should be increased in Bijie area.Combined with the actual needs of the mine,the equipment for preventing outburst is recommended.关键词
