The whole machine adopts a modular design, is small in size, can be quickly disassembled, and is more suitable for the drilling needs of small and medium-sized mines. It uses fully mechanized operations and remote control operation, providing a good working environment and high safety.It is equipped with a fault diagnosis system that can quickly identify and solve problems; the automatic unloading rod system fundamentally avoids safety hazards from manual operations.

Before the Raise borer Machine arrived at Yudu Yujie Mining,after-sales engineer Jiao Chaohui was dispatched to the site,responsible for the preliminary preparation work:
 

including equipment going underground (including cages, horizontal shafts, inclined shafts, ramps), tunnel transportation,chamberspecifications (including size specifications and azimuth), stability of the chamber roof (whether support is needed), water chamber specifications, hoisting anchor rods (including position and specifications), equipment foundation (including vertical and inclined shafts), and water and electricity supply (including cable specifications, water supply, etc.) technical guidance to ensure that the conditions for starting work are met.

And provide theoretical training for mining operators, covering topics such as the operating principles of Raise borer Machines, common fault handling, drilling machine transportation and construction configuration, and safety technical operating procedures..

Due to the small tunnel dimensions at Yudu Yujie Mining, the Raise borer Machineuses a rail-drag transport method, separating the front frame and pump station for underground transport.

During the equipment construction period, two after-sales engineers from Yier Technology provided full guidance for the construction of the first mine, responsible for the equipmentfrom positioning, erecting the machine, pilot hole drilling, hanging the cutter head, reaming, retrieving the machine, to retrieving the cutter headand other technical guidance throughout the construction process, ensuring full-process service.

They also taught the mining staff construction experience on-site. After a month of continuous practice and observation, the mining staff have mastered the pilot hole and reaming operations. They also have a preliminary understanding of the problems and solutions that arose during the construction process, laying a solid foundation for future independent construction.

This shaft is designed with an inclination of 72°,to ensure the drilling progress requirements, after-sales engineer Jiao Chaohuistrictly controlled the operation of the drilling machine to ensure that the movement trajectory of the drill bit remained consistent with the preset angle. This includes adjusting the drilling speed, drilling pressure, and other parameters to adapt to different strata and geological conditions.

During the drilling process,after-sales engineer Jiao Chaohui oftenusesa clinometerto monitor the trend of the well inclination changes. Once an increase or exceeding standard trend in well inclination is detected, corresponding measures are taken to adjust.
 

Efforts do not betray those who are diligent. After a month of hard work,the first shaft of Yudu Yujie Mining was successfully completed, with smooth walls and minimal deviation, meeting the expected requirements.

As a manufacturer of Raise borer Machines and down-the-hole drilling rigs, Yier Technology is committed to providing customers with efficient and reliable drilling solutions. In the future, it will continue to leverage its professional advantages in the drilling field to provide strong support for the successful completion of subsequent projects.
