在煤矿生产的采、掘、装、运、支等主要作业过程中,都有大量的粉尘和有害气体产生,严重污染工作环境,影响矿井安全生产和工人的身体健康.因此,如何有效地减少粉尘的产生是现代化矿井生产中不可忽视的问题.煤科院重庆所与镇江煤矿专用设备厂,在引进英国技术的基础上,研制生产了SCF-6型湿式除尘风机,1985年在我矿试用,取得了较好的效果.一、概况阳泉四矿位于沁水煤田之东北边缘,主采12号层、15号层两层煤,煤层赋存较稳定.15号层为优质无烟煤,厚6～7米.历年矿井沼气等级和二氧化碳的鉴定结果,均为高沼气矿井,瓦斯相对涌出量为14.91米~3/吨.煤
In the main operations of mining, digging, loading, transporting and supporting, there are a lot of dust and harmful gases in the coal mine production, which seriously pollute the working environment and affect mine safety in production and the health of workers. Therefore, how to effectively reduce The production of dust is a problem that can not be neglected in the production of modern coal mines. Coal Institute Chongqing and Zhenjiang Coal Mine Special Equipment Factory, on the basis of the introduction of British technology, developed and produced the SCF-6 wet dust blower fan. , Has achieved good results.A general Yangquan four mines located in the northeastern edge of Qinshui coalfield, the main mining layer 12, layer 15 two layers of coal, coal seams more stable.Continuous layer 15 is high-quality anthracite, thick 6 ~ 7m.The results of biogas grade and carbon dioxide identification in previous years are all high methane gas mines with a relative gas emission of 14.91m3 / t
