Problems solved by technology

[0005] The technical problem to be solved by the present invention: the surveying and mapping levels in the mining subsidence areas of the coal mining area currently on the market cannot meet the requirements for use. It is placed on the ground surface and tilted into the soil, and the inclination degree on both sides of the level bracket is different, so it is difficult to adjust, which will affect the detection accuracy of the level

Abstract

The invention relates to the technical field of coal mining, in particular to a surveying and mapping level gauge for a mining subsidence area in a coal mining area, which comprises a level gauge body, a transmission mechanism, a reducing mechanism and a foot stool, the foot stool is arranged, the transmission mechanism and the reducing mechanism are matched with each other, and the foot stool comprises three support rods; the height of the foot stool can be adjusted and the area of the end face of one end, far away from the level gauge body, of the foot stool can be changed while a worker can adjust the height of the foot stool according to the hardness of earth surface soil of a subsidence area and different subsidence degrees of one ends, far away from the level gauge body, of the three supporting rods, so that the subsidence condition of the foot stool is improved; the phenomenon that the detection precision is influenced by different sinking degrees of three supporting rods due to different hardness degrees of earth surface soil is reduced, and in addition, through mutual matching of a transmission mechanism and a reducing mechanism, the situation that the foot stool is covered with soil due to sinking of the foot stool, and the later cleaning difficulty is large can also be reduced.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a surveying and mapping level in a mining subsidence area of ​​a coal mining area. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Under-ground coal mines generally refer to underground mining tunnels when the coal seam is far from the surface. When the surface is very close, it is generally chosen to directly peel off the surface soil layer to excavate coal; most of the coal mines in my country are underground coal mines. When a lake is formed, the size of the subsidence area needs to be calculated at this time. The staff often needs to use a level to measure, and during the measurement process, the level needs to be supported by a tripod and adjusted to the level before it can be used normally. [0003] However, the surveying and mapp...
