Abstract

The special heating pipeline robot for coalbed methane thermal recovery includes a ground coiler, a generator, a ground control center and several groups of hollow pipeline robots. The ground coiler is equipped with an intelligent cable winch, and the intelligent cable winch is wound with a To pull the cable, the outlet end of the intelligent cable winch is provided with a first tension sensor, several groups of hollow pipeline robot groups are arranged side by side at intervals, and two adjacent groups of hollow pipeline robot groups are connected by an electromagnetic docking device; in summary, the present invention High degree of automation, easy operation, good coal dust removal effect, and improved coalbed methane mining efficiency.

Description

technical field [0001] The invention belongs to the technical field of coalbed methane mining, and in particular relates to a special heating pipeline robot for thermal mining of coalbed methane. Background technique [0002] Coalbed methane refers to the hydrocarbon gas stored in coal seams with methane as the main component, mainly adsorbed on the surface of coal matrix particles, and partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal and belongs to unconventional Natural gas is a clean, high-quality energy and chemical raw material that has risen internationally in the past ten or twenty years. Due to the generally low permeability of coal seams in my country, the methods and effects of gas drainage are greatly limited. Therefore, how to increase the permeability of coal seams to achieve the purpose of strengthening gas drainage is an important issue facing the coal industry. Experts at home and abroad have propose...
