Rock and ore sample magnetic parameter measurement device and method thereof for geological exploring

Abstract

The present invention discloses a rock and ore sample magnetic parameter measurement device and method thereof for geological exploring. The device comprises a supporting plate, a supporting bar, an arc angle regulation rack, a cantboard, a specimen box, a probe, an adjustable pole, a horizontal bubble instrument, a precision pin and a laser emitter. The laser emitter and the arc angle regulation rack are employed to correct the inclined angle of an incline plate of the device prior to the measurement, and the accuracy the disposing position of the specimen is improved. The horizontal bubble instrument is able to better calibrate the accuracy of the position of the supporting plate. Besides, the probe and the supporting plate are integrally arranged and are very convenient for using, a sliding block and a spherical hinge are used for easily regulating the position of the probe, the measurement of the distance between the probe and the specimen box are convenient, and the measurement precision and the measurement efficiency are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of geological exploration, and in particular relates to a magnetic parameter measuring device and method for rock ore specimens used in geological exploration. Background technique [0002] In order to understand the magnetic characteristics of rocks and ores in a timely manner during the high-precision magnetic surveying process, guide the magnetic surveying work and correctly interpret the magnetic surveying data, it is necessary to carry out the determination and research of the magnetic parameters of the rocks and ores at the same time as the magnetic surveying work. The rocks and ores in the study area The characteristics of magnetic parameters are the physical prerequisite for the effectiveness of magnetic prospecting and exploration, and also the objective basis for forward calculation and inversion interpretation of magnetic anomalies, which are of fundamental significance. For magnetic prospecting, ...

Problems solved by technology

This method requires a special device for placing specimens. Although various types of measuring devices have appeared at present, although the current special device has a simple structure, it is not reasonable. When measuring, it is easy to place the specimen on an inclined plane. Inaccurate, the inclination adjustment is not accurate, and cannot match the local magnetic inclination. Moreover, in the high magnetic latitude area, because the inclination of the specimens is not accurate enough, the specimens are not easy to be placed stably and accurately. If the specimen position is not determined accurately, It will cause a deviation in the distance from the center of the probe (observation point) to the center of the specimen, which will affect the measurement accuracy

Moreover, when in use, the positions of the probe and the inclined plane are difficult to align well, which also affects the measurement efficiency and measurement accuracy to a certain extent
