为了总结经验,改进工作,我们选择省内开采中发现问题较多的十二对矿井做了探采对比调查,通过分析研究,对有关勘探工作的几个主要问题,提出一些讨论意见。一、勘探与开采对比进行探采对比的矿井,有大同雁崖、挖金湾,轩岗焦家寨,西山西铭、官地、杜儿坪,汾西张家庄,霍县南下庄,阳泉二矿,潞安王庄、五阳,晋城四新。此外,还有一些矿井做了部分探采对比调查。开采验证表明,总的来说,在探明主要地质构造、煤层、煤质、水文地质、开采技术
In order to summarize the experience and improve the work, we chose 12 pairs of mines found more problems in the province to conduct a survey of exploration and mining, through analysis and research, on the exploration of several major issues, put forward some comments. First, the exploration and mining contrast exploration and mining of the mine, a Datong Yan cliff, dig Golden Bay, Xuan Gang Jiaozhai Xishan Ximing, Guan Di, Du Erping, Fenxi Zhangjiazhuang, Huoxian Nanzhuang Zhuang, Yangquan II Mine, Luan Wang Zhuang, Wuyang, Jincheng four new. In addition, some mines do some exploration and comparison. Mining verification shows that, on the whole, in the identification of the main geological structure, coal, coal, hydrogeology, mining technology
