在上卡姆钾盐矿床开采钾盐层时,记录到200多次喷出强度达4500吨的气体动力现象,其特点是显现形式和条件的多样性,可区分为自身突然喷出,伴有瓦斯喷出的突然崩落和混合型的突然崩落。基本上采用房式采矿法开采厚2.0～6.5米的相邻的两层钾盐层。所开采的各钾盐层没有喷出危险,气体动力现象发生于相邻的

In the exploitation of potassium salt in the Upper Kamenny Potash Deposit, more than 200 gas dynamic phenomena with a discharge strength of 4,500 tons were recorded, which were characterized by the diversity of forms and conditions that could be distinguished as sudden discharges of themselves accompanied by Sudden collapse of gas ejection and sudden collapse of the hybrid. Basically, the use of room mining method mining thickness of 2.0 to 6.5 meters of the adjacent two layers of potassium salt. The exploitation of each potash layer is not dangerous to spurt, and the gas dynamic phenomenon occurs in the adjacent
