Description

Technical Field

[0001] The utility model relates to the field of mine rocks, in particular to a rock blasting sampling device for mining geological collection. Background Art

[0002] Rock blasting in mines is one of the important means of mining. It uses the explosive effect of explosives to apply load to rocks, causing the mechanical process of rock destruction. When the explosion detonates in the rock, the high-temperature and high-pressure shock wave generated will shatter the rocks around the blast hole; the explosion shock wave will produce tangential tensile stress in the rock, causing radial cracks and annular cracks to develop toward the free surface. When reaching the free surface, the compression stress wave is reflected from the free surface into a tensile stress wave, overcoming the tensile strength of the rock and breaking the rock. The rock will fall off, and as the reflected wave continues to propagate, all the rocks within the blasting funnel will be broken.

[0003] Before rock blasting, it is necessary to sample the rocks in the blasting area to facilitate the arrangement of the amount of explosives. Currently, when sampling rocks, the crushed stones are usually collected directly. However, the sampling accuracy of the crushed stones is not high, and it is difficult to collect the ore in the rock layer, which in turn affects the accuracy of rock blasting sampling. Therefore, we propose a rock blasting sampling device for mining geological collection to solve the above problems. Utility Model Content
