Title: Innovations of Quan Lou in Coal-Rock Dynamic Disaster Management
Introduction
Quan Lou is an innovative inventor based in Beijing, China. He has made significant contributions to the field of safety engineering, particularly in the area of coal-rock dynamic disaster management. His work focuses on developing methods to enhance safety in underground mining operations.
Latest Patents
Quan Lou holds a patent for a method of locating coal-rock main fractures by utilizing electromagnetic radiation from precursors of coal-rock dynamic disasters. This innovative method involves the arrangement of at least four groups of three-component electromagnetic sensors in underground tunnels. Each group consists of three directive antennas that receive electromagnetic signals orthogonal to each other. The monitoring host collects these signals, ensuring synchronous reception by different sensors through an atomic clock. By performing vector superposition on the strengths of the electromagnetic signals, the direction of the magnetic field line is determined. Consequently, the planes of electromagnetic wave propagation perpendicular to this direction are established. The location of the coal-rock fracture is identified at the intersection point of these planes, providing a reliable method for disaster prevention.
