摘　　要：为确定新疆106煤矿在未充分垮落采空区下的1803工作面溜子道合理布置位置,以新疆106煤矿的实际地质工况为背景,通过理论分析和数值模拟的方法,对1803溜子道的合理布置位置进行了研究。通过理论分析得到了未充分垮落结构下的垂直应力分布规律,并得到了巷道合理布置的理论范围。通过数值软件模拟了新疆106煤矿现场地质特征,基于理论分析对1803溜子道的不同布置方案进行模拟,结果表明在距上采空区遗留煤柱中心35~45 m是合理的溜子道布置范围,在此区域内布置溜子道可以有效避开高应力区。In order to determine the reasonable layout position of transportation roadway in No.1803 Face of Xinjiang No.106 Mine under the insufficient caving goaf,the actual geological conditions of Xinjiang No.106 Mine was taken as the background,the reasonable layout position of No.1803 transportation was studied by theoretical analysis and numerical simulation.Through theoretical analysis,the vertical stress distribution law under the insufficient caving structure was obtained,and the theoretical range of the reasonable layout of the roadway was obtained.The geological characteristics of Xinjiang No.106 Mine were simulated by numerical software.Based on theoretical analysis,different layout schemes of transportation roadway were simulated.The results showed that the range of 35~45 m from the center of coal pillar in the upper goaf section was a reasonable layout range.In this area,the arrangement of transportation roadway could effectively avoid the high stress area.
