By rock crushing manner and the type of tool that can be divided into Dayton drilling and rotary drilling. In geological work, the use of drilling equipment to drill into underground smaller diameter, depth larger columnar hole, known as drilling. Drilling diameter and depth sizes, depending on the purpose of drilling and mineral burial depth. Drilling for oil and gas drilling and groundwater are larger in diameter. The main function of the kind of information ① get underground, that take core, mine heart, debris, liquid samples from drilling and other gaseous samples. ② as geophysical logging channels, access to a variety of geophysical field rock layer information. ③ observation as an artificial channel aquifers hydrogeological dynamics. ④ used for exploration, mining, developers groundwater, oil and gas, geothermal drilling. By use of drilling engineering usually use is divided into geological survey or exploration drilling, hydrogeological drilling, wells or engineering geological drilling, geothermal drilling, oil drilling, coal drilling, ore field drilling, drilling and other construction ground.
