Description

Technical Field

[0001] The utility model belongs to the technical field of underground rock layer detection in coal mines, and particularly relates to a rock layer detection recorder. Background Art

[0002] Mine pressure and rock layer control are important methods to ensure safe and efficient production in underground coal mines. During coal mine excavation, it is necessary to conduct drilling detection of the overlying rock layer on the working face, deformation and damage of the surrounding rock of the tunnel, and the distribution of the output status and lithology changes of the coal-bearing strata. The current rock layer detection recorder can only extend the probe into a certain depth in the borehole according to the measurement point layout plan. Because it cannot be determined whether the drilling angle is consistent with the plan, it cannot ensure that the probe is placed in the required position. In the process of detection by the probe, although the damage of the surrounding rock mass and the degree of crack development can be detected, the angle of crack expansion, extension and distribution cannot be determined. Therefore, the function of the current rock layer detector has certain limitations and cannot meet the detection requirements. Utility Model Content
