煤炭是重要的能源，在我国整个能源结构中占80％以上。归中国煤炭工业发展十分缓慢，仅在少部份省区有几处初具规模的煤矿，临解放时年产原煤仅3000多万吨，勘探工作落后，装备陈旧，只有少量比较简陋的日本利根300m手把钻机和蒸汽钻。新中国成立以后，党和国家十分重视煤炭工业的发展，至今煤产量已增加了20多倍，煤田勘探工作随之有了很大发展，在各省区建立了煤田勘探队100多个，开动上千台钻机，完成钻探工程量6800多万米，探明了数千亿吨储量，为我国煤炭工业的发展提供了可靠的资源。作为煤田勘探的重要方法——钻探工程也有了显著的变化和发展，并且除从事煤田地质勘探外，还进行井筒冻结孔、矿山注浆孔、水井、工程地质勘察、露天边坡勘探、建筑基础桩等工程施工。
Coal is an important source of energy, accounting for more than 80% of China’s entire energy mix. Due to the slow development of China’s coal industry, only a few large coal mines in the few provinces and autonomous regions have begun to take shape. Only about 30 million tons of coal are produced annually when the project is liberated, with outdated exploration and outdated equipment and only a few relatively simple Japanese roots 300m hand drill and steam drill. After the founding of New China, the party and the state attached great importance to the development of the coal industry. Since then, coal production has increased by more than 20 times. Coalfield exploration work has greatly improved. Over 100 coalfield exploration teams have been established in all provinces and autonomous regions. Thousands of rigs have completed more than 68 million drilling projects and have proven reserves of several hundred billion tons, providing reliable resources for the development of China’s coal industry. As an important method of coalfield exploration - drilling engineering has also been a significant change and development, and in addition to engage in coalfield geological exploration, but also for the wellbore freezing hole, grouting holes, wells, engineering geological survey, open slope exploration, building foundation Pile construction.
