【摘要】 针对红透山矿井开采规模扩大,同时产生铜矿深部开采所面临的通风路线长、阻力大;作业面工作面多,风量不足,作业面环境恶化等问题,提出了对其东部通风系统进行改造的方案。对红透山铜矿通风系统进行实验,并在其测试结果的基础上,采用图解法对其进行计算、分析验证该改造方案的可行性,并提出了对该矿东部通风系统降阻的途径。更多还原

【Abstract】 The expansion of the underground mining capacity and the mining at an increasing depth in Hongtoushan Copper Mine have brought the problems of long ventilation route, great ventilation resistance, many working faces and insufficient air flow rate, leading to a deteriorated environment at the working face. A plan for transforming its east ventilation system was put forward. Testing was carried out on the mine’s ventilation system. Based on the testing results, graphic method was used to compute and analyze the feasibility of this transformation plan and the measures for reducing the resistance of the east ventilation system were proposed.更多还原
