摘　　要：针对新建矿井A、B 2个煤层无揭露评估数据,地勘钻孔数据较少且可靠性差等问题,选取同属一个瓦斯地质单元的邻近对应煤层的坚固性系数、瓦斯放散初速度、煤层瓦斯压力、煤的破坏类型等相关评估参数,进行新建矿井A、B煤层评估。随埋藏深度变化回归分析,结果表明,A、B煤层分别在埋深574 m和180 m以浅,各项评估参数没有同时达到或超过临界值,可以确定新建矿井的A、B煤层分别在埋深574 m和180 m以浅无突出危险性。邻近煤层数据在新建矿井突出危险性评估中发挥了重要作用。In response to the problems of no disclosure evaluation data in the two coal seams of the new mine A and B,and the scarcity and poor reliability of the geological survey borehole data,the relevant evaluation parameters such as the solidity coefficient,gas dispersion initial velocity,seam gas pressure and coal damage type of the adjacent coal seams belonging to the same gas geological unit were selected to evaluate the coal seams of the new mines.The results of the regression analysis with the depth of burial showed that the A and B seams were shallow at 574 m and 180 m,respectively,and the evaluation parameters do not simultaneously reach or exceed the critical values.Neighbouring coal seam data played an important role in the assessment in new mines.
