本溪煤矿因斜井下延,原有地面主扇供给的风量满足不了生产需要,提出在井下安装一台轴流式主扇,并于1973年8月27日投产,至今运转效果良好,解决了生产急需.但这与《煤矿安全生产试行规程》第135条规定不符,如在地面安装主扇,因电车道水平以上漏风严重,如另开巷道,需时很长,影响目前井下生产,如何认识这个新生事物,请有关同志发表意见.来函请投至本刊编辑部。
Benxi coal mine due to inclined shaft downwards, the original supply of the main wind on the ground can not meet the production needs of the wind, put forward a well installed in the shaft of an axial fan, and put into operation on August 27, 1973, has run well and solved the production Urgently needed.However, this is inconsistent with the provisions of Article 135 of the Code of Practice for Work Safety in Coal Mines. For example, installing main fans on the ground and serious air leakage above the level of the tramways, such as opening of tunnels, takes a long time to affect the current underground production. This new thing, please comrades express their views. Please send a letter to the editorial department.
