An intelligent control method for efficient extraction of coalbed methane in goafs includes judging whether extracting the coalbed methane in each goaf or not by utilizing a mobile mining pump station or constructing a fixed downhole extraction pipe network and according to whether concentration of CH4 in the goafs, a working face and a return gasway exceeds the standard or not. In addition, the control method includes real-time monitoring of other gas compositions and gas temperature restricting extraction of the coalbed methane, and the gas compositions include ethylene, carbon monoxide and oxygen. The invention particularly provides the intelligent control method for efficient extraction of the coalbed methane in the goafs. During application and practice, the method basically solves the problems of independent operation and single extraction control parameter in each goaf, no safety control guarantee during extraction process and low extraction efficiency. Prospective objective of system ...

Provided is a magnetic coupling gearbox. The magnetic coupling gearbox comprises an input assembly, a box body, an oil-water line system, an output assembly, a speed control gear system, a speed control gear system base seat, an output shaft, an oil return pipe and an output end flange. The input assembly is coupled with the output assembly through magnetic force, adjustable air gaps are arranged between the input assembly and the output assembly, and the speed control gear system is connected with the output assembly and installed on the speed control gear system base seat. The output shaft is connected with the speed control gear system, the output end flange is arranged on the box body, and the oil-water line system is connected with the oil return pipe. The input assembly is steel rotors with copper rings, and the output assembly is permanent-magnetic stators and is aluminum stators with permanent-magnetic materials. The magnetic coupling gearbox has the advantages of solving the problems ...
