Embodiment Construction

[0015] The construction method of turning head-on and crossing the tunnel roadway is realized by the following steps:

[0016] First: Belt conveyors are used for transportation during tunneling. Before turning, the tail of the belt conveyor is retracted one shift in advance, and a 40-ton slide (scraper conveyor) is installed on the belt conveyor to ensure that the unit (excavation) before turning machine) excavation along the chute, the chute is moved to the side of the tunnel roadway opposite to the position of the traversing opening, the head of the chute is 30 meters away from the side of the opening, the cutting head of the unit is at the traversing opening, and the reload of the unit rides on the smooth part of the chute; excavation along the trough roadway During the transportation process, slides are used, and the slides only need to be moved to the side of the roadway opposite to the position across the opening;

[0017] Second: Change the pin connection between the un...

Abstract

The invention relates to a coal mining process, in particular to a gate roadway head-on turning transverse construction method. By the method, the problems of low efficiency, low safety, high labor intensity of workers and the like in the conventional gate roadway head-on turning transverse construction method are solved. In the gate roadway head-on turning transverse construction method, a machine set coal cutting mode is combined with a vibrating canon firing mode; coal is output by a machine set; and a scraper-trough conveyer is used for tunneling by 3 to 4 meters every day, so that time is obviously saved, the coal cutting speed is increased, and the tunneling speed is effectively increased. The scraper-trough conveyer is used for tunneling, so derailing difficultly occurs during transportation, the problems of belt deflection, derailing and the like caused by the use of a belt are solved, and electromechanical accident rate is reduced. The coal is output by the machine set, so the coal shoveling amount of the workers is reduced and the labor intensity of the workers is reduced. The coal is cut and output by the machine set, so the safety coefficient is greatly increased.

Description

technical field [0001] The invention relates to an excavation process, in particular to a construction method of turning head-on and crossing along a tunnel roadway. Background technique [0002] In the early stage of preparation for fully mechanized mining, underground coal mines need to prepare tunnel roadways to ensure ventilation, transportation and other requirements. For high-yield and high-efficiency mines, there are more than one tunnel roadways. For example, the 1306 coal mining face of Zhaozhuang Coal Industry has a total length of 220 meters. It adopts a three-inlet and two-circle ventilation method, that is, three air inlet lanes and two return air lanes. It is necessary to excavate 5 parallel channels. In order to meet the ventilation and transportation requirements between the troughs, the construction must be connected across the troughs, and the traversing and troughs must be arranged vertically. According to the design requirements, the total length of the ...
