Coal mine TBM advanced exploration split type remote control drilling machine and advanced exploration construction method

Abstract

The invention relates to a drilling machine and a construction method, belongs to the technical field of drilling, and particularly relates to a coal mine TBM (Tunnel Boring Machine) advanced exploration split type remote control drilling machine and an advanced exploration construction method. Compared with a conventional TBM advanced exploration drilling machine with the construction capacity of 30-50 m, the drilling machine is a special deep hole drilling machine with the larger torque and propulsive force, advanced drilling construction of deep holes with the length larger than 300 m can be completed, for coal mine roadway tunneling construction with the mandatory requirement of exploration before tunneling, the drilling and tunneling alternating frequency can be greatly reduced, and the comprehensive construction efficiency is effectively improved. The main machine part of the drilling machine is of an independent structure and is arranged on a trailer platform behind a TBM propelling mechanism, and the large-range adjustment of a circumferential angle, a main shaft inclination angle and a working radius can be achieved so as to meet the special advanced hole exploration site requirement of TBM. The drilling machine is controlled through electric control and remote control, and an operation table and a pump station can be flexibly arranged according to the TBM layout. In addition, the invention further provides the advanced exploration construction method suitable for the coal mine TBM.

Description

technical field [0001] The invention relates to a drilling rig and a construction method, belonging to the technical field of drilling, in particular to a coal mine TBM advance exploration split type remote control drilling rig and an advance exploration construction method. [0002] technical background [0003] In recent years, coal mine rock roadway excavation has become an important factor restricting the further efficient and high-quality development of the coal industry. At present, most of the underground roadheaders in my country's coal mines are cantilever type roadheaders and traditional drilling and blasting methods, which have technical problems such as unbalanced digging and bolting, low efficiency of roadway formation, and poor safety. Compared with traditional construction methods, the full-face hard rock tunnel boring machine TBM (Tunnel Boring Machine) can realize continuous rock breaking, rock loading, reloading, support, spraying and dust prevention, etc. ...

Problems solved by technology

However, there are problems such as large construction depth, complex geological conditions, and the inability to accurately predict the ground design and exploration in the tunneling construction of underground coal mines. stipulates that the construction of advanced exploration drilling shall be finalized as a mandatory regulation

[0004] Although the current conventional TBMs are all equipped with advanced exploration drilling rigs, they generally adopt the top punch type, and the short-distance drilling effect is acceptable, and the torque and propulsion force are relatively small (the torque does not exceed 1000Nm, and the propulsion force is about 10-20kN) , the single drilling depth generally does not exceed 30-50m. For the coal mine roadway construction with the mandatory requirement of "explore first and then dig", the frequent alternation of drilling and excavation has a great impact on the efficiency of roadway excavation. In addition, The diameter of the drilling tool used in the top punch drilling rig is generally small. During the drilling process, it is prone to deflection caused by the combined action of propulsion force, rotational torque and shock wave, which affects the accuracy of advanced detection. These problems greatly restrict the use of TBM equipment. Further popularization and application of underground coal mines
