摘要
利用统计分析、模糊推理等多种手段,提出一种煤巷围岩稳定性综合分类法,研究平顶山矿区煤巷稳定性变化规律,得到了评价围岩稳定性的统计判据,可根据巷道条件及实测信息评价巷道稳定程度,并绘制出多指标围岩分类图,直观表达了样本及样本分布规律,既提高了分类的可靠性,又简化了分类方法。开发出煤及半1煤岩巷锚梁网支护专家系统,该专家系统通用于煤巷锚梁网支护系列选型,并在平顶山矿区得到成功应用。
The overall classification for rock stability of coal roadway was derived. The statistical criterion for appraising rock stability was obtained by studying the coal roadways in Pingdingshan mining area. Based on roadway's conditions and measured information, the stability degree was evaluated and the multi-index rock classification figure was drawn. The principle of rock bolting in coal roadways was also described. The expert system was also opened up. The expert system is applicable for the site types of anchor girder net. Its practical test in Pingdingshan coal area proved successful.
