▎ 摘　　要

NOVELTY - Use of graphene with a specific structure in the preparation of dust suppressants for coal mines. The graphene with a specific structure is prepared by oxidizing the flake graphite and intercalating with sulfuric acid and potassium permanganate and obtained by mechanical peeling. USE - The graphene with a specific structure is useful in preparing dust suppressants for coal mines (claimed). ADVANTAGE - The method: has a structure similar to that of coal dust, so graphene can be adsorbed with tiny coal dust and then settle, and the sedimentation efficiency is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) coal mine dust suppressant, comprising 0.1-3 wt.% anionic surfactant, 0.1-3 wt.% nonionic surfactant, 0.1-3 wt.% graphene with special structure, 100 wt.% aqueous solution; and (2) Preparing the coal mine dust suppressant comprising taking anionic surfactant and nonionic surfactant according to the dosage ratio, dissolving in partially deionized water graphene with specific structure is used as solution B, separately storing, completely stirring solution A, solution B and remaining deionized water to obtain the coal mine dust suppressant.
