煤峪口矿回风联巷探陷落柱的设计

Design of Collapse Column in Return Air Lane of Meiyukou Mine

为了解决传统陷落煤柱勘探方式所存在的勘探流程繁琐、效率低下,陷落柱探测效果差的难题,煤峪口矿回风联巷施工过程中提出了一种新的探陷落煤柱方案,采用YCS40矿用瞬变电磁仪以瞬变电法方案对陷落柱实现探测,根据实际应用结构表明该探陷落柱方案将陷落柱的探测精度提升了75%,探测时所用的探测时间降低了47%。

In order to solve the problems of complicated exploration process,low efficiency and poor detection effect of collapsed coal pillars existing in traditional exploration methods of collapsed coal pillars,a new scheme of detecting collapsed coal pillars was put forward in the construction process of return air roadway in Meiyukou Mine.The YCS40 mine transient electromagnetic instrument was used to detect collapsed coal pillars by transient transformation method.According to the practical application structure,the detection accuracy of collapsed coal pillars was improved by 75%and the detection time was reduced by 47%.
