Gas extraction drilling method for intelligent mine and robot system thereof

Abstract

The invention discloses a gas extraction drilling method for an intelligent mine and a robot system thereof. The robot system comprises a drilling subsystem (1), a roadway continuous pipe operation machine (2) and a roadway positioning subsystem (3), wherein the roadway continuous pipe operation machine (2) is connected with the drilling subsystem (1) and the roadway positioning subsystem (3), the drilling subsystem (1) comprises a continuous pipe (4), a drilling crawler (5), an orientator (6), a hole bottom power drilling tool (7) and a drill bit (8) which are sequentially connected from a hole opening to the hole bottom, the roadway continuous pipe operation machine (2) comprises a roller (13), a motor (14), a drilling fluid pump (16), a water tank (17) and a cable penetrating continuous pipe sealing joint (18), and the roadway positioning subsystem (3) comprises a detector (19), a three-axis fluxgate A (20) and a shallow hole (21). According to the robot system, the gas drilling efficiency and the understanding precision of the coal seam geological structure are greatly improved, the number of drilling construction personnel is reduced, and the labor intensity of workers is relieved.

Description

Technical field [0001] The present invention relates to the field of mine gas drainage process, in particular, it relates to a method and gas drilling robot system for mines wisdom. Background technique [0002] Yin Wasi coal mining process in the presence of a huge coal mining safety hazards, such as gas explosion, gas outburst, seriously endangering the lives of mine workers and caused huge economic losses. Therefore, an existing underground mining, mining tunnel excavation when the treated coal seam drilling, coal seam gas facilitating the overflow and reduce gas disaster. However, in reality exclude coal mine gas drilling, some companies or construction workers to reduce the workload, cost savings, often reduce the drilling depth while drilling, making the excavation to be inadequate gas emissions from coal, a potential hazard. General mine gas drainage drilling depth of about 100m, is safe drilling depth of the current design, but in practice, most of the drilling depth of o...

Problems solved by technology

However, in actual coal mine drilling to remove gas, some enterprises or construction personnel often reduce the drilling depth when drilling in order to reduce the workload and save costs, so that the gas emission in the coal seam to be excavated is insufficient, causing potential hazards.

Generally, the depth of drilling holes for gas drainage in coal mines is about 100m, which is the currently designed safe drilling depth. In practice, most drilling depths are only 50% of the designed drilling depth, which seriously affects the safety of subsequent mining work.

[0003] In the prior art, the device for measuring the drilling depth mainly has the following disadvantages: the stroke of the drilling machine piston in the device is measured to obtain the drilling depth, and the piston stroke can be set artificially, which is easy to change and cannot truly reflect the drilling depth ; In addition, the accuracy and efficiency of gas drilling are generally not high, and the work intensity of workers and the price of drilling equipment are relatively high
