一、概述 近年来,随着能源需求的不断增加,煤田地质勘探工作普遍展开,原来一些已经发现或发现后未进一步工作的矿区,又重新组织了钻探工作;为寻找隐伏矿体,钻孔深度愈来愈大;为扩大远景,地质构造多数较为复杂,同时在边远地区也开展了新的煤矿资源勘探。以往认为难于施工,钻进技术要求高的矿区,现在又开展了工作。这些矿区
I. Overview In recent years, with the continuous increase of energy demand, coalfield geology exploration work has been carried out in general. Some original mining areas that have been discovered or found without further work have reorganized the drilling work. In order to find hidden ore body, the depth of drilling In order to enlarge the prospect, most of the geological structures are more complicated, and at the same time, new exploration of coal resources is also carried out in remote areas. In the past that difficult to construction, drilling high technical requirements of the mining area, and now carried out the work. These mines
