摘要
针对矿山18线南西翼矿体开采过程中存在的通风系统不完善、风量欠缺、污风无法及时排出等问题,运用风压平衡原理、网络优化技术、机站优化技术以及计算机网络模拟技术展开研究,拟定了3种可行的通风方案。经技术经济比较,确定了新掘18线905~855 m回风井( 1.5 m),保留该井905 m水平回风机站,并在855 m水平新设1台K45-6-№12风机(18.5 kW)方案。数值模拟结果表明18线南西翼通风系统总风量达到20.5 m^3/s,井下风流的可调性和稳定性增强,为矿山的安全生产提供了有力保障。
Aiming at the problems of imperfect ventilation system,insufficient air volume and dirty air not being discharged in time during the mining process of the south-west wing orebody on the 18th line of the mine,three feasible ventilation schemes have been worked out by using the principle of air pressure balance,network optimization technology,optimization technology of air station and computer network simulation technology.Through technical and economic comparison,on the basis of making full use of existing ventilation facilities and ventilation shaft and roadway engineering,a new 905~855 m return air shaft(1.5 m)along 18 lines and a new K45-6-12 fan(18.5 kW)at 855 m level in this well are determined to improve the working environment in this area.The numerical simulation results show that the total air volume of the south-west wing ventilation system of line 18 reaches 20.5 m^3/s,and the adjustability and stability of the underground air flow are enhanced,which provides a strong guarantee for the safe production of the mine.
