Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] Such as figure 1 , 2 As shown in the figure, a construction method of a large-scale mining high-end full-mechanized excavator as a channel to pass through a collapsed column frame without legs, in which conventional support is carried out in the area of the collapsed column, and then I-beams 1 and single beams are used for the conventional support. The body column 2 erects a legless shed; one end of the I-shaped steel beam 1 penetrates into the top of the hydraulic support 3 by no less than 500mm and is connected to the roof of the roadway by the top of the hydraulic support 3, and the other end of the I-shaped steel beam 1 is close to the coal side and is sheeted The body column 2 is connected to the roof of the roadway; two I-shaped steel beams 1 are supported on a hydraulic support 3, and the distance between two adjacent I-shaped steel beams 1 is not greater t...

The invention relates to an underground coal mine roadway supporting technology, in particular to a large mining height end-mining fully-mechanized excavating machine manufacturing removing frame channel collapse column passing leg-less supporting erecting construction method. The method comprises the steps that conventional supporting is carried out at a collapse column zone, then H-shaped steel and a single-body column are added, leg-less supports are erected, the supports are fixed into a whole through a pulling rod, one end of each leg-less support is supported by a hydraulic support, the other end of each leg-less support is supported by the single-body column, tight fixing with a top plate is achieved, and when a fully-mechanized excavating machine carries out tunneling below, working can be carried out safely. Stability of the working face top plate is the key factor of coal mine safety, the supporting force of the hydraulic support and the single-body column is fully used, by erecting the leg-less support, the construction cycle is shortened, the labor intensity of workers is lowered, and safety factors are improved.
Description
technical field [0001] The invention relates to a coal mine underground roadway support technology, in particular to a construction method for erecting a legless shed through a collapsed column by a fully mechanized excavator for a large mining height and end mining, and is suitable for the large mining height working face to pass through a collapsed removal channel Post frame shed alleyway. Background technique [0002] At present, it is a new type of production technology to use the fully-mechanized excavator at the end of the working face with a large mining height as the withdrawal channel. The roof support of the roadway has been unable to meet. The invention solves the problem of roof support in the subsidence area in the channel for removing the frame well by adding I-beams to the top plate in the subsidence area and erecting a legless shed support. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the roof is bro...
