局部通风是煤矿安全生产的主要基础工作,局部通风管理的核心是风量管理。掘进工作面所需风量,必须保证冲淡并排除井巷掘进时产生的有害气体与矿尘,并为人员的健康、掘进效率的提高,提供良好的环境。 根据上述要求,从1987年6～8月对河南省四统配局分属的28对矿井的143个掘进工作面,进行了以工作面风量管理为中心内容的局部通风调查。 调查工作说明:进一步完善局部通风管理仍是一项需要引起重视的安全基础工作;在保证工作面风量的同时,对局部通风要树立效益观念,要做到技术经济合理,局部通风费用最省。
Local ventilation is the main work of coal mine safety production, the core of local ventilation management is the air volume management. The amount of air required for tunneling must ensure dilution and elimination of harmful gases and dust generated during tunneling and provide a good environment for the health of the crew and the improvement of tunneling efficiency. According to the above requirements, from January to August 1987, 143 excavation workfaces of 28 pairs of mines belonging to the 4-unit allocation bureau of Henan Province were investigated, and the local ventilation investigation centered on the air volume management of the working face was conducted. Survey work shows that: to further improve the local ventilation management is still a need to pay attention to the safety of basic work; in ensuring the air flow at the same time, the local ventilation to establish the concept of efficiency, to achieve technical and economic rationality, the most cost-effective local ventilation.
