我矿矿石的外部运输为铁路运输,采用矿仓漏斗装车。以往,矿石常因相互挤压、粘结而在漏斗中粘壁自然成拱,无法自动漏下。曾采用过钢钎捅,铁棒撬,甚至用爆破法来消除矿石自然成拱的状况,但费时费力,既影响装车速度,又严重危及人身安全。为此,我矿“三结合”小组,在有关设计单位的帮助下,经过反复研究和试验,采用由空气压缩机输出的压缩空气,
I mine the external transport of ore for rail transport, using the hopper funnel loading. In the past, ore often due to mutual extrusion, bonding and sticking in the funnel natural arch, can not automatically leak. Had adopted a steel rod poke, iron rod pry, and even use blasting method to eliminate the natural arch of the ore condition, but time-consuming and labor-intensive, both affect the loading speed, but also seriously endanger personal safety. To this end, I mine “triple combination” group, with the help of the design unit, after repeated research and testing, the use of compressed air output by the air compressor,
