Abstract

The invention relates to coal mining equipment, in particular to a drill pipe device for a mine. The drill pipe device includes a drill pipe body, blades, connecting ends and deflection ends, whereinthe outer surface of the drill pipe body is provided with the blades, two ends of the drill pipe body are correspondingly connected with the connecting ends and the deflection ends, and a plurality ofdrill pipe devices for the mine are connected in series through the connecting ends and the deflection ends. According to the drill pipe device for the mine, series connection is realized through themultiple drill pipe devices for the mine, the connection of different numbers of the drill pipe devices for the mine can effectively adjust the length of a whole drill pipe so as to adapt to requirements of the drill pipe length under different environments; and the deflection ends of the drill pipe devices for the mine can be used for realizing the real-time change of a whole drilling path, anddrilling work under complex environments is facilitated.

Description

technical field [0001] The invention relates to coal mining equipment, in particular to a mining drill pipe device. Background technique [0002] In the process of coal mining, the coal content and gas content in different directions are important references for gas control and prevention, as well as coal mine value estimation and development. Due to the complex geological conditions of my country's coal mines, and most coal mines have gas gushing, this has also led to gas becoming one of the important culprits of coal mining accidents in my country, which seriously threatens the safety of coal miners' lives and the improvement of coal mine production efficiency. For example, in 2005, a total of 414 gas accidents occurred in my country's coal mines, resulting in more than 2,000 deaths. By 2008, the number of casualties caused by gas accidents had dropped to 778. In 2010, there were 126 gas accidents, resulting in 593 deaths. In 2016, there were 59 gas accidents across the...
