主平硐在不间断运输下的局部改造

Construction Technology of Large Cross-section Drive Chamber Constructed out of Local Main Chamber under Uninterrupted Transportation Conditions

塔山矿主平硐中部驱动硐室是在已投入使用的主平硐及三联巷局部进行挑顶刷帮改造而成。为确保硐室施工不影响矿井正常生产,该硐室施工方案需充分考虑主平硐的设备设施保护以及施工空间受限等问题,故不同于一般的硐室施工方法。本文就塔山矿主平硐中部驱动硐室的特殊施工方法进行了总结,以期为类似条件下的硐室施工提供借鉴。

The middle drive chamber of main chamber in Tashan Mine is constructed out of cutting the top andbrush the sides in the main chamber has been put into use and local triple roadway.In order to ensure that theconstruction of the chamber does not affect the normal production of the mine,the construction plan of the chambershould take into account the problems such as the protection of the equipments and facilities of the main chamber andthe limited construction space,therefore,it is different from the general chamber construction method.In this paper,thespecial construction method of the middle drive chamber of main chamber in Tashan Mine is summarized,with a view toprovide the reference for the chamber construction under the similar conditions.
