Abstract

The invention discloses a large-section shaft heading machine. The large-section shaft heading machine comprises a downhole main engine, a first-level vertical conveyor, and a second-level vertical conveyor, wherein the first-level vertical conveyor is fixedly connected to the downhole main engine so as to synchronously step along with the downhole main engine, passes through a cutter head and stretches into a guide hole; the bottom end of the second-level vertical conveyor is matched with the top end of the first-level vertical conveyor so as to receive materials on the first-level vertical conveyor; the top end of the second-level vertical conveyor is fixed to the ground; and the length of the second-level vertical conveyor can be extended. The invention also discloses a construction method of the large-section shaft heading machine. The construction method comprises the following steps of: making the guide hole exceeding a shaft-forming depth; causing the bottom end of the first-level vertical conveyor to stretch into the guide hole; driving the cutter head by using a main driving device to rotate for tunneling, and conveying residue soil to the ground by the first-level vertical conveyor and the second-level vertical conveyor in sequence. The large-section shaft heading machine and the construction method thereof can be used for excavating a large-section shaft, have high degree of mechanization, and avoid risks caused when the personnel descend a shaft for construction.

Description

technical field [0001] The invention relates to the technical field of shaft drilling machines, and more specifically relates to a super-large-section shaft boring machine and a construction method thereof. Background technique [0002] In underground projects such as coal mines, metal and non-metal mines, pumped storage hydropower stations, subway machine railway tunnels, etc., a large number of shaft constructions are required. At present, the common drilling technology based on drilling and blasting is widely used, which requires a large number of people to work underground, with high work intensity and poor safety. The mechanized drilling technology and machine drilling method are the future development direction. [0003] Drilling method Drilling is a method of drilling a wellbore by using shaft drilling rigs and other equipment. The advantage of this method is that the staff do not need to go down the well to operate, and the main operations are carried out on the grou...
