Excavation construction method for mine hard rock roadway

Abstract

The invention discloses an excavation construction method for a mine hard rock roadway. A cutting device is used for cutting out the outline of the roadway, cutting in the horizontal direction and in vertical direction is carried out in the outline of the roadway to obtain parallel horizontal cut grooves and parallel vertical cut grooves, and the horizontal cut grooves and the vertical cut grooves intersect and cut the section of the roadway inside the cut grooves of the outline to a longitudinally and transversely intersected grid-shaped structure. A crushing device is used for crushing or breaking a first rock inside the grid-shaped structure of the section of the roadway in a prizing mode and then crushing or breaking other rocks in the prizing mode, the crushed or broke rocks are taken out until all the rocks within the cutting depth are taken out, and a manual or mechanical conveying device is used for conveying cut rocks. The excavation construction method for the mine hard rock roadway resolves the problem of excavation of hard rocks or superhard rocks through a mechanical method, eliminates an explosion work procedure, is safe and efficient, and is not restrained by use and management regulations of explosive products. The roadway is good in forming performance, damage to surrounding rocks is small, supporting can be simplified or eliminated, operation time and engineering cost are saved, the construction speed is improved, and excavation cost is lowered.

Description

technical field [0001] The invention relates to a tunneling construction method of mine shafts, in particular to a tunneling construction method of hard rock shafts in mines. Background technique [0002] Coal mines and other mine shafts all need to adopt the tunneling method to excavate the shaft to meet the requirements of mining construction; the existing technology tunneling methods generally use drilling blasting or tunneling equipment to tunnel, and drilling blasting is to drill and blast in the area that needs to be tunneled. The blast hole used is filled with explosives, and the shock wave and force generated by detonating the explosive will loosen or crack the rocks and soil in the excavation area, so as to facilitate the excavation construction. [0003] The various types of excavation devices of excavation device excavation construction at present all rely on the cutting head rotation of the excavation device to cut rocks with picks to realize rock-breaking excava...
