Problems solved by technology

[0002] At present, in the construction process of the conveyor head chamber, anchor mesh spraying and anchor cable support are generally used as temporary support + reinforced concrete masonry support as permanent support. This support method has a long construction period and consumes funds. Therefore, in line with the principles of shortening the construction period, saving costs and reducing investment, we urgently need to design a new support method

Abstract

The invention discloses a method for supporting a machine head chamber of a large-roadway adhesive tape conveying machine. The method comprises the following steps: firstly, laying an iron wire net, constructing anchor rods and anchor ropes, and performing grouting support with the thickness of 200 mm and the strength of C20. By adopting the method disclosed by the invention, the construction period can be greatly shortened, and precious time for mine acceptance is saved. By adopting the method disclosed by the invention, a great deal of investment is reduced, and millions of investment can be saved when compared with that of conventional design. Along with continuous increase of large-size production mines, strict requirements on construction period and investment control, the problems of long construction period and large investment are solved. Under the pressure of rigorous economic situation of coal at present, the method disclosed by the invention can be definitely widely popularized in later large-size mine construction.

Description

technical field [0001] The invention relates to the technical field of underground support in coal mines, in particular to a support method for a head chamber of a conveyor belt roadway conveyor. Background technique [0002] At present, in the construction process of the conveyor head chamber, anchor mesh spraying and anchor cable support are generally used as temporary support + reinforced concrete masonry support as permanent support. This support method has a long construction period and consumes funds. Therefore, in line with the principles of shortening the construction period, saving costs and reducing investment, we urgently need to design a new support method. Contents of the invention [0003] The purpose of the present invention is in order to solve the problems in the above-mentioned prior art, and provide a kind of brand-new support method of the head chamber of the belt road conveyor. [0004] The present invention is achieved through the following technical...
