Abstract

The invention relates to a mining intelligent drilling pressure relief device and a using method thereof, and belongs to the technical field of coal mining equipment. The device comprises a machine body support, a control system, an identification sensing system and a drilling system, wherein the front end of the machine body support is connected with universal wheels through universal wheel supports, driving wheels are arranged on the two sides of the rear end of the machine body support respectively, the identification sensing system is arranged on the machine body support, the drilling system is arranged at the front end of the machine body support, the control system is arranged at the rear end of the machine body support, and the driving wheels are connected to the control system. According to the device, automatic control is carried out through the control system in the whole process, the pressure relief workload is effectively reduced, meanwhile, construction is facilitated, theconstruction speed is increased, and the construction period is not affected.

Description

technical field [0001] The invention relates to an intelligent drilling pressure relief device for mines and an application method thereof, belonging to the technical field of coal mining equipment. Background technique [0002] As the main energy source in our country, coal occupies an important strategic position in the national economy. In the next few decades, it is difficult to change the coal-based energy structure. With the intensification of coal mining, shallow resources are gradually depleted, and coal development is accelerating to shift to deep and complex geological conditions. There have been roadways with high geostress in kilometers deep wells, roadways with extremely broken surrounding rocks, roadways with extremely large cross-sections, and roadways strongly affected by mining. And complex and difficult roadways such as retaining alleys along the gob. In view of the increasingly complex geological conditions and the increasing instability of ground pressu...
