The invention provides a deep hole charging tamping bar assembly for blasting construction of a coal mine tunnel, as shown in Figure 1, the deep hole charging tamping bar assembly comprises: a joint, the front end of which is located in a blast hole and is coaxial with the blast hole; the telescopic rod is divided into a fixed section and a movable section, and the fixed section and the movable section are coaxially arranged in a sleeving mode and located outside the movable section; the movable section is in threaded connection with the rear end of the connector, and the telescopic rod is used for driving the connector to move back and forth in a blast hole; the connecting rod is in threaded connection with the rear end of the fixed section along the same axis of the blast hole; and the pushing mechanism is connected with the rear end of the connecting rod and used for driving the connector to do linear reciprocating motion in the blast hole after being coaxially connected with the connecting rod, the telescopic rod and the connector so as to compact explosive powder in the blast hole, and the defects that an existing deep hole blasting charging tamping bar is limited in length and inconvenient to use are overcome.
Description
technical field [0001] The invention belongs to the field of deep-hole blasting of coal mine rock, in particular to a deep-hole charge gun stick assembly for blasting construction of coal mine roadway. Background technique [0002] At present, ultra-deep blast holes are used for blasting construction in deep underground tunnels, deep hole loosening blasting construction, deep hole blasting in coal mining face crossing fault rock areas, and deep hole loosening blasting in coal seams, etc. 2.5m or more. In deep hole blasting, the bat for charging is the key to charging. [0003] The existing deep-hole blasting charge bats mainly have the following disadvantages: the existing deep-hole blasting charge bats have the disadvantages of limited length and inconvenient use. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a deep hole charge gun stick assembly for blasting construction of coal mine roadway, so as to solve the problems of limited...
