Problems solved by technology

[0003] At present, automatic drilling rigs have been realized at home and abroad, which can have the functions of automatic loading and unloading of drill pipes, automatic drilling, and wireless remote control operation. Functions such as navigation, perception and independent decision-making need to be developed urgently, and still need to rely on more on-site personnel to assist part of the work; (2) There is no general construction equipment for the follow-up construction operations of drilling, and the supporting construction operations still need to be completed manually, which cannot meet the intelligentization of coal mines Construction Requirements for Drilling

Abstract

The invention discloses a coal mine underground drilling construction equipment system and a construction parameter optimization method thereof. The coal mine underground drilling construction equipment system comprises a drilling unit, an auxiliary transportation unit, a post-processing unit and an intelligent decision-making system and can autonomously complete coal mine underground drilling and back-up construction operation, so that autonomous transportation and obstacle avoidance of all construction equipment are achieved. A roadway deformation failure position and a to-be-constructed area can be detected and found, a construction equipment system can quickly reach a construction site, drilling and all back-up construction operations are independently completed, and manual intervention is not needed. Therefore, the underground coal mine drilling construction equipment system is high in operation efficiency, high in automatic construction efficiency and high in operation precision, all equipment of the drilling machine group can rapidly move and can be matched with one another to complete construction operation, and a theoretical basis is provided for underground coal mine drilling machine group construction.

Description

technical field [0001] The invention relates to the technical field of coal mine underground drilling construction equipment, in particular to an underground coal mine drilling construction equipment system and a construction parameter optimization method thereof. Background technique [0002] With the increase of the mining intensity and depth of underground coal mines, deep coal resources have become the strategic guarantee of my country's main energy source. Due to the environment of high ground stress, high ground temperature, high humidity, high dust, low visibility and strong electromagnetic interference in deep coal mines, construction The operating environment for personnel is harsh. At present, drilling equipment is widely used in coal mine gas control and water exploration and drilling operations. The existing equipment is mainly mechanized drilling rigs, with many operators and high labor intensity. There are potential safety hazards in the construction process. The...
