地下开采运搬工作是井下主要工序之一,最繁重的体力劳动也就是运搬工作。在过去我矿运搬工作几乎全部是用人力,尤其是平巷掘进中的倒掌子和裝車等工序,就更为严重。我矿生产任务是繁重而紧張的,因此对于开拓和探矿,采准的速度要求更为紧迫,必須是快速的。在这些主要水平巷道当中掘进,为了每班多次循环以提高單巷掘进速度,就必須在放完炮及通完风,將工作面石头倒出1.50～2公尺以便进行凿岩。在过去这种倒掌子的主要工具就是簸箕和耙子。首先用耙子将石头倒入簸箕中之后抛出1.50～2公尺以外的距离。这种所谓倒掌子
Underground mining and transport work is one of the main processes downhole, the heaviest manual labor that is moving jobs. In the past, almost all of mine transport and relocation work was done by manpower. In particular, the operation such as pouring a piece of sand and loading a car in the laneway was even more serious. The task of mine production is heavy and tense. Therefore, the speed of quarrying and prospecting is more urgent and must be rapid. In these major horizontal roadway tunneling, in order to cycle multiple times each class to improve the speed of single lane, you must put the gun and pass the wind, the face stone poured 1.50 ~ 2 meters for drilling. In the past, the main tools for this operation were the dustpan and the rake. First throw the stone into a dustpan with a rake and throw a distance of 1.50 to 2 meters. This so-called down the palm
