Abstract
With the rapid development of mining technology in coal mines, the technical requirements for safe production in coal mines are constantly improving. In addition, it is affected by the geological conditions of the coal mine, the section of the roadway and the manpower reduction. There is an increasing demand for automatic and intelligent equipment for coal mine. A crawler-type double-arm rock drilling car which can be operated by wireless remote control is developed. It can be operated by remote control and adjusted manually. It can not only drill small diameter ordinary boreholes, but also drill large boreholes with diameter of 100-120 mm. It can effectively solve the problem of larger free surface in straight-hole cutting blasting. It is safe in operation and high in excavation efficiency.
