Description

TECHNICAL FIELD

[0001] The present application relates to geological exploration, in particular to a measuring device for exploring coal thickness. BACKGROUND

[0002] As an important basic energy in energy structure, the accurate accounting of coal resources reserves, the scientific design of mining scheme and the safety control of production all rely on the accurate measurement of coal seam thickness (hereinafter referred to as "coal thickness"). Coal thickness is not only the core parameter for calculating coal seam reserves and determining the mining boundary, but also the key basis for optimizing the layout of fully mechanized working face, avoiding roof and floor accidents, and improving mining efficiency and resource recovery rate.

[0003] By connecting the hollow rod into the exploration drill hole, the telescopic cone rod is in contact with the bottom of the drill hole and slides upward under pressure, driving the trigger rod to move until the trigger rod is in contact with the induction probe, automatically triggering the operation of the external electromagnetic exploration equipment. Compared with the operation of directly inserting the probe into the drill hole for exploration, the accidental triggering of the probe before it reaches the correct exploration position can be effectively avoided, reducing the risk of misoperation. However, the current measurement method requires the use of drilling equipment first, and then the use of detection equipment, which is relatively cumbersome to switch between the two devices, thereby reducing the measurement efficiency of coal thickness. In addition, the structure is relatively complex and inconvenient to use, as the trigger rod needs to be in contact with the induction probe to know that the probe has reached the specified position for detection.
