Method for determining uniaxial compressive strength of non-actual ore

The invention discloses a method for determining the uniaxial compressive strength of a non-actual ore. The method comprises the following steps: crushing and screening out a to-be-detected non-actual ore material, determining the particle size composition of the to-be-detected material, and classifying the to-be-detected material according to the size fraction; selecting one or more actual ores as contrast materials, carrying out crushing and screening out, determining the particle size compositions of the contrast materials, and classifying the contrast materials according to the same particle size as the to-be-detected material; carrying out an ore grinding test on the to-be-tested material and the contrast materials on the same mill according to the same particle size composition, the same grinding quality and the same ore grinding condition, and drawing an ore grinding curve; and according to the ore grinding curve, determining the time required for grinding to the same fineness, and substituting the tim
