AI Technical Summary

Technical Problem

Existing technologies in deep mining of metal mines have poor ventilation effects due to localized fans, low air intake, poor cooling effect, and high maintenance and management costs, making it difficult to meet the ventilation requirements of deep, high-temperature and high-humidity environments.

Method used

The natural ventilation structure is adopted, which connects the external roadway, the connecting roadway of the stope, the internal roadway of the stope and the return air shaft, reducing the use of local fans. The ventilation system is constructed by using ventilation pipes and branch pipes to directly exhaust the dust and blasting fumes from the working face to the return air system, thereby reducing energy consumption and maintenance costs.

Benefits of technology

It achieves efficient ventilation, ensuring that the intake is filled with fresh air, significantly improving air quality, reducing energy consumption and maintenance costs, avoiding fan overheating and space occupation issues, and improving the safety and equipment efficiency of deep mining.

Abstract

本发明涉及矿井通风领域,尤其涉及金属矿山采场节能通风结构及其施工方法,包括若干条依次施工的开采进路、沿矿体走向设置的脉内巷、采场外与外界联通的脉外巷以及联通脉内巷与脉外巷的采场联巷,脉内巷一端或两端联通回风井,回风井上口连接上中段回风巷,风流依次流经所述脉外巷、采场联巷、脉内巷、开采进路以及回风井,排至上中段回风巷中。本发明构建了基于自然风的高效通风体系,确保了进路内始终充满来自主巷的新鲜风流,作业前后的粉尘、炮烟等其他有毒有害气体直接排至通风管并迅速排出,避免在进路内扩散,无需依赖局部通风风机,通风路径简洁、阻力小、效率高,杜绝了因风机长时间运转发热导致的洞室热负荷增加问题。
