Abstract

The present invention relates to a rapid excavation method for continuous mining and continuous charging working face support roadway, including: step S1 cutting falling coal, step S2 supporting the empty roof area, step S3 permanent support, step S4 moving the support forward, step S5 equipment backward transport, in step S2 S1 is equipped with a self-propelled belt-type transfer vehicle of a fully mechanized excavator. The front end of the fully mechanized excavator is provided with a hardness detection device and a stress detection plate. In step S2, a portal bracket and a portal crawler frame transfer vehicle are configured. In step S3 A single-arm rocker is arranged, and in step S5, a bracket carrier is arranged. In the present invention, the control system selects the initial propulsion speed and the initial cutting speed of the fully mechanized excavator according to the hardness of the coal seam in the branch road, and the control system controls and adjusts the comprehensive excavator according to the comparison between the real-time stress of the fully mechanized excavator and the standard preset range stress value set inside the control system. The propulsion speed and cutting speed of the excavator realize the mining process of intelligent control and adjustment, and maximize the mining efficiency while ensuring the stable operation of the fully mechanized excavator.

Description

technical field

[0001] The invention relates to the technical field of coal mining, in particular to a rapid excavation method for a branch roadway in a continuous mining and continuous charging working face. Background technique

[0002] my country is a big energy country with abundant coal resources, and its output and reserves are in the forefront of the world. As an industrial power fuel, coal is often used in power generation, transportation, metallurgy, etc. At the same time, it is also a very important civil life fuel. Most, most farmers still regard coal as an important living fuel. In addition, coal is also an important chemical raw material. After coking, distillation, etc., many important chemical raw materials and their derivatives can be obtained, such as gas, coal tar, nitrogen fertilizer. , pesticides, plastics, synthetic fibers and other hundreds of products, some coal seams contain gallium, germanium, uranium and other rare or radioactive elements, which can b...
