Based on the principle of multi-wavelength extinction particle-graining technique, the function-constrained solution method is used to solve the size distribution of dust, and a dual-wavelength extinction measurement method for coal mine dust is proposed. This article will introduce the basic principles of dual-wavelength extinction dust measurement, numerical simulation results and the principle of design, and its feasibility and application prospects are discussed.
