如何衡量煤矿通风系统的好坏是通风设计、通风技术管理、通风系统技术改造所面临的首要问题,也是当前急待解决的问题。 等积孔是缪尔格( M.Murge)在一个世纪前提出来的,再拿当时的通风指标来衡量发展了一百多年的煤炭科学技术的今天,显然不能适应生产实际的需要。在使用等积孔中主要存在两个问题:一是等积孔不能客观地、全面地反映矿井通风的难易程度、通风技术及通风管理水平;二是由于各生产矿井的自然条件和采用的技术方法不同,使等积孔失去了可比性。本文针对等积孔存在的问题提出综合指标来评估煤矿通风系统。
How to measure the quality of the coal mine ventilation system is the most important issue in the ventilation design, ventilation technology management and ventilation system technical innovation, and is also an urgent problem to be solved. The isocial cavity was put forward by M. Murge a century ago. When we use the current ventilation index to measure the development of coal science and technology for over one hundred years, it obviously can not meet the actual needs of production. There are two main problems in the use of isobaric holes: one is that the equivalent hole can not objectively and comprehensively reflect the difficulty of mine ventilation, ventilation technology and ventilation management; second, due to the natural conditions and the adopted Different technical methods, so that equivalent hole lost comparability. In this paper, a comprehensive index is proposed to evaluate the ventilation system in coal mines for the problems of isoporous pores.
