Description

A kind of fast excavation equipment for coal roadway

technical field

The invention relates to the technical field of coal mine roadway construction, in particular to a coal roadway rapid excavation equipment.

Background technique

The excavation operation of the roadway is a prerequisite for all other mining operations in coal mine production. With the substantial improvement of the working efficiency of the mining face, the contradiction that the roadway excavation speed cannot keep up with the mining demand is becoming more and more prominent in many mining areas. Safe, fast and efficient roadway excavation and support technology is a necessary condition to ensure high production and high efficiency in coal mines. At present, there are three main methods for mechanized and rapid excavation of underground tunnels in coal mines: the first one is the traditional single tunnel tunneling, the main equipment of the working face are roadheaders and bolters; the second one is double tunnel tunneling, which uses continuous shearers for tunneling. , this tunneling mode is equipped with an advanced bolter rig. The third type is the single tunnel excavation of the bolt-digger integrated machine. However, the above three technologies and equipment have the following shortcomings: tunneling, anchoring, cross operation, low production efficiency and poor safety; the operation of the bolt-cutting unit that integrates the continuous shearer and the bolt-digger can only play its role when the roof is strong. The performance of rapid excavation has poor adaptability to working conditions; the distance to the top of the top is large, and the time of the top of the top is long, which has potential safety hazards.

In the Chinese invention patent document with the publication number of CN109538224A, a new type of fast roadheader for coal roadway is disclosed. The cutting device adopted by the roadheader adopts a retractable drum to cut and excavate up and down, which can meet the requirements of various working faces of roadway sections. 2. While the cutting device excavates the section, the top bolt drilling rig system and the supporting bolt drilling rig system can realize parallel operation, realize the parallel operation of tunneling and anchoring, and improve the Efficiency of excavation work. 3. The present invention adopts the front and rear support excavation method, which has good adaptability to the top surface, bottom surface and side rails. At the same time, the equipment has a small distance between the top and the bottom. When passing through the fault structure belt and the broken coal seam, it can effectively reduce the risk of top-falling accidents. ; Enhance adaptability and improve construction safety factor. 4. The adjustable shield body and the back support shield have protective functions to ensure the safety of equipment and operators. The negative pressure technology is used to remove dust and effectively improve the working environment. The invention has the advantages of strong geological adaptability, high tunneling efficiency, high degree of mechanization and safe operation, and has high popularization value.
