The umbrella-type drilling rig is a drilling equipment specially developed for the implementation of mechanized vertical excavation. It is like an umbrella. It can be used to drill blastholes when it is opened, and it can be conveniently transported when it is closed. It is an indispensable special equipment for achieving rapid well drilling, shortening the well construction cycle, and improving economic benefits.
The umbrella-type drilling rig is applicable to a wide range of wells, from small wells of 4.5 meters to 5 meters, medium-sized wells of 6 meters to 7 meters, and large wells of 8 meters to 8 meters or more. According to the continuous development of blasting technology, the umbrella-type drilling rig provides blasthole depths of 4200 mm, 4800 mm and 5500 mm, which meets the technical requirements for deep hole smooth blasting and greatly improves the speed of vertical shaft excavation. The umbrella-type drilling rig can not only drill blastholes, but also can be equipped with an efficient YGZ70 rock drill to drill 40-meter-deep drainage holes, water exploration holes and grouting holes. Therefore, the umbrella-type drilling rig is currently an ideal vertical shaft excavation and drilling equipment at home and abroad.
