笔者于1977年曾随煤炭部地质、地球物理考查团赴德意志联邦共和国进行为期三周的考查。在德期间走访的单位有萨尔煤矿公司、亚琛矿山联合协会、鲁尔煤矿公司、埃森煤矿研究院、普拉克拉—蔡司莫斯物探公司等十多个单位。在地质方面我们很注意西德的煤田地质勘探手段的运用、勘探方法、勘探程度等方面的课题。笔者仅就亚琛矿山联合协会给我们介绍的对于一个新井田如何运用地面地震勘探、钻探、由邻近矿井巷探等综合勘探手段以取得最佳、最经济效果的综合评定方法,介绍如下:
In 1977, the author went to the Federal Republic of Germany for a three-week examination with the Department of Geology and Geophysical Expeditions of the Ministry of Coal Industry. During the visit to Germany units Saar Coal Company, Aachen Coal Mining Association, Ruhr coal mining company, Essen Coal Research Institute, Prachara - Zeiss Moss geophysical company more than 10 units. In geology we pay great attention to the use of geological prospecting tools in western Germany, exploration methods, exploration and other issues. The author gives an overview of how to use the comprehensive exploration method of surface exploration, drilling, roadway exploration by neighboring mines, etc. to obtain the best and most economical results from the Aachen Coal Mining Association, as follows:
