煤田开采前必须进行地质勘测以为煤矿生产设计提供科学有效的数据,在煤炭地质勘测中钻孔技术对地测数据的准确性有重要的影响。本文首先对煤田钻探技术进行分析,然后详细讨论了煤田勘探中各个地层的组成和特点,以及与之相适应的钻探方法和注意事项。
Before coal mining, geological survey must be conducted to provide scientific and effective data for coal mine production design. Drilling technology in coal geological survey has an important influence on the accuracy of geodetic data. This paper first analyzes the coalfield drilling technology, and then discusses in detail the composition and characteristics of various strata in coalfield exploration, and the corresponding drilling methods and precautions.
