The invention belongs to the technical field of large volume surface cutting, and particularly relates to a guide cutting structure for linear back cutting and a linear back cutting method of the guide cutting structure. The guide cutting structure is characterized by comprising a guide rod, a guide wheel connected to one end of the guide rod, and a directional rope pulley connected to the other end of the guide rod; the position of the guide wheel on the guide rod can be adjusted vertically, and the guide direction of the guide wheel in the horizontal plane is adjustable; a cutting positioning piece is arranged between the guide wheel and the rope pulley, the cutting positioning piece is located on the guide rod, and the position of the cutting positioning piece on the guide rod is adjustable. The guide cutting structure for the linear back cutting and the linear back cutting method of the guide cutting structure have the beneficial effects that the defects of an existing surroundingtype cutting technology are overcome, on the basis of the prior art, non-winding type reverse cutting can be expanded, disturbance is greatly reduced, the drilling footage speed of a single working face is increased, the squaring efficiency is improved, the situation of edge line repairing caused by squaring and excavation is reduced, and the production time is shortened.
Description
technical field [0001] The invention belongs to the technical field of large-volume surface cutting, and in particular relates to a guiding cutting structure for linear reverse cutting and a linear reverse cutting method. Background technique [0002] At present, the excavation construction on a single working face is mostly broken by pneumatic picks. The noise reduction measures for the smashing of pneumatic picks do not carry out the work of pneumatic picks during the rest time of residents. Do a good job of explaining the surrounding communities, so that the construction on the construction site during normal hours will not disturb the residents, and set up anti-noise facilities for the wind pick construction process. When performing closed enclosure sound insulation or arranging drilling, it is time-consuming and labor-intensive, and the construction progress is slow; the labor intensity is high, the sidelines are irregular, and the sidelines are easy to be damaged, and ...
