北海道各煤矿一直趋于深部开采,如幌 内煤矿开采深度已达1250m。今后,如何再 次开发利用这些地下空间,日本对此进行了 多方面的探讨。 一、原有井下设备的利用 1.利用原有井下设备的优点 众所周知,神冈煤矿是一个老矿,该矿 利用原有的部分井下设备,以改造采掘以外 的生产项目为目的,进行开发和利用;砂川 煤矿正在试验把立井改成无重力设备。这些 事例都有一个共同的特点:即改造利用原有 矿山井上、井下设备,从而大大缩短了设计 周期。这样做有以下优点:
Hokkaido coal mines have been tending to deep mining, such as Sapporo coal mining depth has reached 1250m. In the future, how to develop and utilize these underground spaces again will be explored in various aspects by Japan. First, the use of the original underground equipment 1. The advantages of using the original underground equipment As we all know, is an old mine in Kamioka Coal Mine, the mine part of the original underground equipment, to transform the production of mining projects for the purpose of development and Utilize; Shachuan Coal Mine is testing the shaft into a gravity-free equipment. All of these cases have one common characteristic: the transformation of the original mine uphole and downhole equipment, thus greatly reducing the design cycle. This has the following advantages:
