Abstract

The invention discloses a rock mining device and method for crossing broken zone surrounding rock, and belongs to the field of mining. According to the device, a steel box culvert is arranged on a flat car; power of the flat car is provided by an electric locomotive connected with the flat car, a slag loading tank car is arranged at the other end of the electric locomotive, and the travel of the flat car, the electric locomotive and the slag loading tank car is provided by a track laid on the ground; and drilling equipment and an automatic slag discharging device are arranged in the steel boxculvert, and the automatic slag discharging device is used for conveying slag of the drilling equipment into the slag loading tank car from the steel box culvert. The problem that workers are harmed due to the fact that the wall caving phenomenon is prone to occurring during existing roadway tunneling is solved, the mining method is free of the processes of drilling and grouting, the use amount ofsteel bars and concrete is greatly reduced, tunneling and permanent supporting can be carried out at the same time, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of mining, and in particular relates to a rock mining device and a mining method for passing through surrounding rocks in a broken zone. Background technique [0002] During the excavation of mine roadways, due to the limitation of geological survey technology or insufficient survey, a large number of discontinuities with different sizes and shapes are often encountered, such as joints, beddings, faults, etc. In the process of excavating the broken zone, the safety is poor, and engineering accidents such as collapse and falling are very prone to occur. Roadway roof collapse will cause damage to mechanical equipment, increase investment costs, delay excavation progress, and pose a huge threat to the safety of on-site operators. Therefore, high requirements are placed on the quality of support. [0003] At present, the main methods for supporting and crossing the broken zone in tunnel construction include grouting fill...
