Description

Technical Field

[0001] The utility model belongs to the technical field of mining acceptance, in particular to an auxiliary device for acceptance of mining volume in a comprehensive mining field. Background Art

[0002] The comprehensive method of acceptance of mining volume in a stope requires the cooperation of field work and internal work to calculate the mining volume. The field work is as follows: before measuring the stope, the nearest measurement control point must be found first, a branch wire must be drawn using a hanging compass and a tape measure, and then a best control point A that can measure the entire stope is laid out, and a fan-shaped wire network is laid out using point A. Each fan-shaped wire must be measured for azimuth and inclination with a hanging compass, and the slope distance with a tape measure. The horizontal thickness of the ore body is measured at each measuring point using a distance meter. The measured points must be marked to keep a basis for the next measurement until the stope is closed, and the data must be recorded to facilitate internal mapping and calculation; the internal work is as follows: the horizontal projection map is drawn using the fan-shaped wire and the broken step data measured on site, and the profile map is drawn for each fan-shaped wire, and the vertical thickness of the stope h1, h2, h3... is measured on the profile map. The measured vertical thickness is averaged to obtain H, and the horizontal projection area S is measured on the map to calculate the mining volume, which is then calculated as follows: mining volume = S*H*specific gravity. Compared with existing methods, this method can reduce labor and greatly improve on-site work efficiency. The personnel stay in the exposed area for a short time, which greatly reduces safety risks. It can also truly reflect the true thickness of the ore body, provide a reliable basis for subsequent mining, and effectively ensure the mining loss depletion rate.

[0003] When using the comprehensive method for acceptance of mining volume in a mine, auxiliary devices such as a tape measure, a measuring compass, and a rangefinder are required. When using the measuring compass, the measuring compass is generally held in hand and corrected to the level, and then the angle is read. During this process, the hand will shake, resulting in measurement errors. Therefore, it is necessary to design an auxiliary device for acceptance of mining volume in a comprehensive method to solve the above problem. Utility Model Content
