Novel coal mine anchoring agent installing device and method

Abstract

The invention relates to an anchoring agent installing technology in coal mine roadway support, in particular to a novel coal mine anchoring agent installing device and a novel coal mine anchoring agent installing method. According to the novel coal mine anchoring agent installing device and the novel coal mine anchoring agent installing method, the problems that an anchoring agent easily breaks, easily deflects and easily falls off in an installing process are solved. The novel coal mine anchoring agent installing device comprises a cylindrical brittle plastic protective shell, wherein an opening is formed in each of the upper end and the lower end of the cylindrical brittle plastic protective shell; a partition plate is arranged in the inner cavity of the cylindrical brittle plastic protective shell, and partitions the inner cavity of the cylindrical brittle plastic protective shell into an upper primary cavity and a lower secondary cavity; the length of the upper primary cavity is greater than that of the lower secondary cavity; internal screw threads are formed in the inside surface of the upper part of the cylindrical brittle plastic protective shell; external screw threads are formed in the outside surface of the lower part of the cylindrical brittle plastic protective shell; grid stripes are rolled on the outside surface of the cylindrical brittle plastic protective shell; two axial cutting seams are formed in the side surface of the cylindrical brittle plastic protective shell in a penetrating manner, and directly face each other. The novel coal mine anchoring agent installing device and the novel coal mine anchoring agent installing method are applicable to the coal mine roadway support.

Description

technical field [0001] The invention relates to an anchoring agent installation technology in coal mine roadway support, in particular to a novel coal mine anchoring agent installation device and method. Background technique [0002] In the process of coal mining, the overlying strata will exert great pressure on the roadway, making it difficult to ensure safe and efficient production by relying on its own strength. Therefore, it is very necessary to support the roadway. At present, using bolts and anchor cables to support the roadway has become a commonly used roadway support method in coal mines. The specific method is: firstly drill holes on the roof, and then install the anchoring agent (the installation of the anchoring agent refers to: first The anchoring agent is pushed to the bottom of the borehole, and then the anchoring agent is crushed), thereby anchoring the anchor rod or anchor cable to the roof. The anchoring agent is generally separated from the cement and th...
