某矿六矿组G60米以上采用平峒溜井开拓.西入风井标高763米,和640主运平峒高差为123米,矿内外的温差将有利于自然通风的形成.春秋两季自然风压作用不大时,利用分布在各区段风机进行辅助通风.夏季矿内气温低于矿外,风流下行.前几年,由于采掘工作基本集中在700米以上,自然风流从西人风井进入,至700峒口排出,风流线路短漏风少,工作面污风和烟尘排出较快,自然通风基本满足了生产的需要.近年来,由于生产的发展,采矿和采准工作已下降到670水平,各生产水平与640主运手峒贯通的各种井巷增多了,风路增长,漏风点增多,
The G60 mine of Gansu 6 ore group is developed with Pingtong chute, the height of west wind shaft is 763 meters, and the elevation difference of 123 meters for main transportation is 123 meters, the temperature difference between inside and outside of the mine will be conducive to the formation of natural ventilation. When the pressure is not strong, the use of distributed in the fan section of the auxiliary ventilation. Summer in the mine temperature is lower than the mine, the Merry downstream .As a few years ago, due to the basic mining work concentrated in the 700 meters above the natural wind from the West into the wind , To 700 峒 mouth discharge, short wind leakage lines less, work surface dirt and smoke discharge faster, natural ventilation basically meet the production needs.In recent years, due to the development of production, mining and mining work has dropped to 670 level , All kinds of shafts and culverts that have reached the level of 640 with the main transport operations have increased in number of production levels, the number of air outlets has increased,
