【摘要】 翠宏山铁多金属矿山属于大型地下矿,矿体规模大,连续性较好,多阶段同时开采,坑内巷道纵横交错,通风网络较为复杂。因此,井下通风系统必须可靠、有效,以保证采场及各工作面具有足够的风量。本文主要对两种通风方案进行了优化论证。更多还原

【Abstract】 Cuihong mountain iron polymetallic ore is a large underground ore and ore body scale is big with good continuity. The pit lane are arranged in a crisscross pattern,so the ventilation network is more complex,and if multiple stages mining operated,mine ventilation system must be effective,reliable,in order to ensure ensure sufficient air flow in the mining area and the working face. This article mainly discusses the two ventilation schemes optimized.更多还原
