为了更加深入地探究各因素对煤层底板破坏带的影响程度,以肥城矿区底板破坏带实测数据为基础,利用灰色关联分析方法建立评价模型,并通过MATLAB软件进行分析和计算,得到各影响因素的关联度。研究结果表明,各影响因素对破坏带的影响程度依次为工作面斜长、采深、倾角、采厚,可以为煤矿底板安全事故的预防及管理提供参考价值。
In order to further explore the impact of various factors on the coal seam floor damage zone, based on the measured data of the floor damage zone in Feicheng mining area, the gray relational analysis method was used to establish the evaluation model and analyzed and calculated by MATLAB software to get the influencing factors Correlation. The results show that the influence degree of each influencing factor on the failure zone is in turn inclined length, mining depth, dip angle and mining thickness, which can provide reference value for the prevention and management of coal mine floor accident.
