Title: Innovations of Xiaofei Liu in Coal Mining Technology
Introduction
Xiaofei Liu is a notable inventor based in Jiangsu, China, recognized for his contributions to coal mining technology. With a total of 3 patents, Liu has developed innovative methods that enhance the efficiency and safety of coal extraction processes.
Latest Patents
One of Liu's latest patents is a fluidized coal mining method utilizing self-energy storage of a coal seam. This method involves developing a mine roadway, actively uncovering coal, mining coal in fluidization, and backfilling a goaf. The process induces a dynamic phenomenon by uncovering coal actively, establishing a coal-mining drilling well from the ground to the coal seam, and subjecting the coal seam to hydraulic in-situ cutting. The resulting coal-rock mixture flows into a roadway system, where coal, gangue, and water are separated and recycled in a subsequent circulating coal mining process.
Another significant patent is the inversion calculation method of coal-bed gas parameters of fast test while-drilling. This method allows for real-time testing of gas flow and concentration during drilling, enabling accurate calculations of coal-bed gas pressure and content without occupying drilling time. The invention is noted for its accuracy, convenience, and speed, making it a valuable tool for coal mining operations.
