针对同时服务于煤层瓦斯预抽、采空区瓦斯抽采和高抽巷抽采的瓦斯抽采系统,从不同抽采方式对抽采负压的不同要求、瓦斯分源抽采和利用等方面分析了分3套系统建设的必要性;结合某矿+470 m水平的实际情况,分析了井下临时泵站分三系统建设的可行性;+470 m水平井下临时过渡瓦斯抽采泵站分3套系统建设取得了良好的效果。
In view of the gas drainage system that also serves the pre-pumping of coal seam gas, the gas extraction of goaf and the extraction of high pumping tunnel, the different requirements of different extraction methods on the negative pressure of extraction and extraction and utilization of gas sources The necessity of sub-system construction is analyzed. According to the actual situation of a mine with the level of +470 m, the feasibility of sub-three temporary underground pumping station system construction is analyzed. The temporary sub-level gas drainage pump station at +470 m level is divided into 3 System construction has achieved good results.
