我公司617队某矿区350中段坑探工程,设计总任务为四千多米,主要探矿坑道长度为1960米,其中石门长度810米。对这么长的坑道,在通风问题上如何结合地质勘探工作特点,选择适宜的通风方式和风筒规格,还缺乏经验。经过反复实践,采用抽出式通风和直径为430—470毫米的铁皮风筒(原设计为500毫米,为利用现有材料,将规格改为430—470毫
My company 617 team a mining 350 mid-section pit project, the total design task for more than 4000 meters, the main prospecting tunnel length of 1960 meters, of which 810 meters Shimen length. For such a long tunnel, how to combine the characteristics of geological prospecting work on the ventilation problem, and select the suitable ventilation mode and the specification of the blower, but also lack of experience. After repeated practice, the use of extracted ventilation and a diameter of 430-470 mm iron tube (original design is 500 mm, to use existing materials, the specifications to 430-470 milliliters
