为了及时滿足国家工农业生产建設的需要,最近我們編审了一个地下开采煤田和一个露天开采煤田的地质勘探設計。这次編制和审查地质勘探設計,在方法上,改变了以往习慣的只是在室內由少数人按規范套的办法,而采取了現場調查与整理、利用已有資 In order to meet the needs of the country’s industrial and agricultural production and construction in a timely manner, we recently compiled a geological prospecting design for an underground coalfield and an open-pit coalfield. The preparation and review of geological exploration designs this time has changed the methods used in the past. Only a small number of people used the standard set of methods in the interior, and on-site investigations were carried out and the existing resources were used.
