目前坑道机械掘进所使用的风、电动力机械,对于地质勘探短浅井、坑施工极不适应,这些机械功率大,重量大,不便运输,使用及附属设备时功率浪费也大,这给地质勘探短浅井、坑机械化带来很大困难。如在义乌某工区,只25华里没有公路,动员了50多个劳力,花了三天时间,把两套笨重的设备拉上山,在某矿区最高的山上(相对高度300多米)搞机掘,一百多人拉了四天,才把压风、发电设备拉上山顶。本文仅将地质勘探短浅井、坑轻便机械化的选型、配套及施工生产情况介绍于下:
At present, the wind and electromechanical machinery used in excavation of tunnel machinery are very unsuitable for the construction of short shallow wells and pit in geological exploration. These mechanical power are large in weight and heavy in weight, so that the power waste in transportation, use and ancillary equipment is also large, Short and shallow wells, pit mechanization brought great difficulties. For example, in a work area in Yiwu, there were no roads in 25 Wuli and mobilized more than 50 labors. It took three days to pull two heavy equipment up the mountain and excavate at the highest mountain in a mining area (relative height of 300 meters) More than a hundred people pulled for four days, before the wind pressure, power generation equipment to the top. This article will only short geological exploration geological wells, pits light mechanization of the selection, construction and production facilities introduced in the next:
