Abstract

The invention discloses an ultra-high-speed water flow cylindrical coal sample preparation device. The device includes an upper box body and a lower box body. The upper box body is a coal sample cutting part, and the lower box body is used for processing an annular coal sample. part, the lower box includes a coal sample fixing clip, and the upper box and the lower box are separated by a box partition; the bottom surface of the lower box is provided with a coal sample fixing clip, and the coal sample The fixing clips are two wooden splints, and the wooden splints are respectively fixed to the side walls of the lower box by column screws; the bottom of the upper box is equipped with a coal sample fixing device, and the coal sample fixing device is left 1. Two clamps matched with the right, the opposite surfaces of the left and right clamps are respectively provided with grooves for fixing coal samples, and a wear-resistant plate is also provided between the coal sample fixing device and the box partition. Using ultra-high-speed water flow to cut coal samples, the coal samples receive less vibration, the coal samples are not easy to break, and the success rate of coal sample preparation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of experimental instruments for coal sample preparation, in particular to an ultra-high-speed water flow cylindrical coal sample preparation device and a preparation method. Background technique [0002] Coal sample preparation is an essential and important step for coal mine-related experiments. Due to the special physical properties of coal and the influence of the external environment: the Poisson's ratio and compressive strength of coal are quite different from those of the surrounding rock, and at the same time, due to the influence of the internal stress of the formation, the coal sample is easily broken and difficult to make Standard samples are subsequently subjected to further experimental testing and analysis. [0003] The current popular coal sample preparation device mainly uses mechanical blades for cutting. Due to the large pressure and vibration applied to the coal sample during the process, ...
