Design construction method of coal mine mining roadway

Abstract

The invention provides a design construction method of a coal mine mining roadway. The method comprises the following steps that firstly, an air return roadway stone gate, a transportation roadway stone gate, an air return roadway, a transport roadway and a cut hole are constructed; secondly, lock foot pipe seam type anchor rod holes are constructed on the bottom corners of the two sides of the roadway; thirdly, the bottoms of the lock foot pipe seam type anchor rod holes are blasted; fourthly, pipe seam type anchor rods are mounted in the lock foot pipe seam type anchor rod holes, and grouting is carried out; fifthly, a dinting manner is adopted for cleaning the bump portion of the roadway; sixthly, a pressure relief groove is excavated; and seventhly, a concrete terrace is constructed. Compared with the prior art, the method is reasonable in structure, construction of the coal mine mining roadway is facilitated, the mining roadway heaving floor is avoided, and safety is high.

Description

technical field [0001] The invention relates to a method for designing and constructing coal mine recovery roadways, belonging to the technical field of coal mine recovery roadways. Background technique [0002] Coal mining roadway: the roadway that forms the coal mining face and serves it during coal mining. Belonging to this type of roadway are: the cut eye of the coal mining face, the section transportation level roadway, and the section return air level wayway. Roadway maintenance workers should be staffed by personnel who are familiar with roof management and support methods, who have the skills of tunneling and mining support and back column operations, and who have mastered the operation methods of pneumatic picks, pneumatic drills, and electric drills. [0003] Floor heaving often occurs in the existing coal mining roadway, which leads to serious deformation of the roadway, and the size does not meet the requirements of coal mine safety regulations. The method ofte...

AI Technical Summary

Problems solved by technology

The existing technology avoids the impact of secondary mining on the stone gate of the mining area by improving the design of the mining roadway, and reduces the number of mining impacts caused by the coal mining work on the stone gate roadway in the mining area, thereby greatly reducing the maintenance times of the stone gate roadway in the mining area. To solve the current situation of difficult support and frequent maintenance of Shimen roadway in the mining area, there is an urgent need for a coal mine mining roadway design and construction method to solve the above problems
