克兹洛夫煤田属于极复杂的矿山地质条件。开采深度大(800~1000米),围岩坚硬,煤的强度高,这些条件都促进了冲击地压的形成和发生。在国内冲击地压出现的记载上,一半以上的冲击地压发生在克兹洛夫矿区。这个矿区有4个煤层,厚度从0.7米到4.5~5米,大多数矿井开采2~3层。煤层属近距离煤层,倾角0~86度,层间距2~25米。煤层的直接顶板和底板基本上是厚为50米的坚硬难于垮落的石英砂岩。
Kloslov coalfield is a very complex geological conditions of the mine. Mining depth (800 ~ 1000 meters), the surrounding rock hard, coal, high strength, these conditions have contributed to the formation and occurrence of rockburst. Occurred in the domestic impact of pressure on the records, more than half of the impact pressure occurred in the Kzlov mine. The mine has 4 coal seams, ranging in thickness from 0.7 to 4.5 to 5 meters and most of the mines mined from 2 to 3 floors. The coal seam is close to the coal seam, dip angle of 0 to 86 degrees, spacing of 2 to 25 meters. The direct roof and floor of the coal seam are basically hard and hard-to-collapse quartz sandstones that are 50 meters thick.
