Abstract

The invention discloses a raise-boring machine construction method. The raise-boring machine construction method includes the steps of construction preparation, drilling machine mounting and construction. The construction preparation step includes building a drilling machine base, digging a pool at a position with a certain distance from the drilling machine base, and digging two sedimentation ditches between a drilling center and the pool, wherein one of the sedimentation ditches is connected with the pool. The drilling machine mounting step includes coinciding the rotating center of a drill bit with the center line of a drilling machine and fastening a gap clamp, wherein a rectangular thread is clamped by the gap clamp when a screw is demounted in place during vertical drilling or drilling machine withdrawal. The construction step includes drilling a hole downwardly by a guide drill 201mm in diameter, and reaming a hole by a reamer bit 1200mm in diameter after communication. The raise-boring machine construction method has the advantages that conveying sequence of a main machine of the raise-boring machine can be adjusted correspondingly according to space size and mine conditions of a construction place, so that construction is performed effectively and rapidly; the two sedimentation ditches are dug, so that effective sedimentation of slurry brought out by flushing fluid is enhanced, and in-place flushing of the slurry of the drill holes is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mine excavation construction, in particular to a construction method of a raise drilling rig. Background technique [0002] In the construction of soft rock mines, the traditional manual excavation of small pilot shafts is used for the construction of shafts and inclined shafts, which has the disadvantages of difficult groundwater discharge, difficult slag removal, poor ventilation conditions, and difficulty in ensuring the construction safety of vertical crossing operations, making the vertical shaft The construction of inclined shafts and inclined shafts is more difficult, especially the construction of vertical shafts and inclined shafts with a height difference or a length greater than 100m is even more difficult. The use of raise drilling rigs to construct pilot wells is a safe, efficient, economical, short construction period and less resource allocation construction technology. [0003] Raise dril...
