Abstract

The special heating method for coal bed gas thermal recovery includes the following steps: Step 1. The length of the coal seam to be thermally mined is L, and the ground control center, the generator and the ground coiler are placed on the ground above the coal seam, and the ground coiler is placed on the ground An intelligent cable winch is installed, and a high-temperature-resistant and tensile cable is wound on the intelligent cable winch. The machine phase is connected, and the other end of the high-temperature-resistant tensile cable is connected with the hollow pipeline robot group at the rear; in summary, the present invention has a high degree of automation, is easy to operate, has a good coal dust removal effect, and improves the mining efficiency of coalbed methane .

Description

technical field [0001] The invention belongs to the technical field of coal bed gas exploitation, and in particular relates to a special heating method for coal bed gas thermal recovery. 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 proposed some me...
