上卡姆钾盐矿区第二和第三别列兹尼科夫矿井田的开采,由于以岩盐和瓦斯突出以及岩盐冒落和随后的瓦斯释放等方式形成的矿山压力动态显现而复杂化了。已记录到140多次瓦斯动态显现。钾盐矿山压力显现的特征具有多种多样的形式和条件,这是因为显现形式和条件与大量因素有关。在瓦斯发生动态显现时并未
The mining of the second and third Bereznikov minefields in the Upper Kamenny potash mine has been complicated by the dynamic pressure of the mines, which are formed by rock salt and gas outburst and rock salt fall and subsequent gas release. Has recorded more than 140 gas dynamic show. The characteristics of stress appearing in potash mines have a wide variety of forms and conditions because of the large number of factors associated with their appearance and conditions. Not seen in the dynamic appearance of gas
