本文论述了地面气候条件变化对矿井安全的影响,通过考查认为:就中梁山矿条件来讲,高水平气温气压变化势态与低水平基本一致。但低水平变化幅度大于高水平变化幅度;在高温低压季节内低水平平峒入风量下降,并出现两个死风点,而高水平平峒入风量增高;由于高、低水平之高程差而产生自然风压,这个风压大于或等于风机作用于平峒口的压力,于是发生停风或反风。 This paper discusses the impact of ground climatic conditions on the mine safety. According to the examination, it is concluded that the changing trend of high level air temperature and pressure is basically the same as the low level. But the change range of low level is greater than that of high level. During the period of high temperature and low pressure, the air intake of low level flat is decreased and two dead spots appear, while the air intake of high level flat is increased. Due to the difference of elevation between high and low levels Produce natural wind pressure, the wind pressure is greater than or equal to the fan pressure acting on the flat mouth, then stop wind or wind.
