Description

Device for measuring slope inclination angle of step

Technical Field

The utility model relates to the field of inclination angle measurement, in particular to a device for measuring the inclination angle of a step slope.

Background

In the production process of an open mine, the slope inclination of the step is taken as one of important parameters, great influence exists on mine production and safety, the slope inclination of the step is too small to cause the reduction of ore recovery rate, the economic loss of the mine is directly caused, the slope safety coefficient is reduced due to the too large slope inclination of the step, and landslide risks are generated. Therefore, the slope inclination angle of the step must be ensured to be consistent with the design inclination angle in the surface mine exploitation process.

In the actual production process of the surface mine, the step slope is not a uniform slope, the middle part of the slope may be sunken, the traditional inclination measuring tool is not suitable for inclination measurement of the non-uniform slope, an expensive surveying instrument is used for measuring the step, and then the inclination of the step slope is obtained through calculation. Therefore, the utility model provides a device which has simple structure, low cost and simple operation and can effectively measure the slope inclination of the concave step slope.
