The invention discloses a top and bottom plate directional measurement exploring tube based on a gravity effect and directional detection equipment. The top and bottom plate directional measurement exploring tube based on the gravity effect is sequentially connected with a first damping unit, a gravity eccentricity measurement exploring tube and a second damping unit in the axial direction, wherein the first damping unit and the second damping unit jointly drive the gravity eccentricity measurement exploring tube to axially and freely rotate by 360 degrees; and under the action of gravity eccentricity, the measuring direction of the gravity eccentricity measurement exploring tube is always positioned on the gravity vertical line of a to-be-measured coal seam. The top and bottom plate directional measurement exploring tube based on the gravity effect is designed in a gravity eccentricity manner, and rolling bearings are arranged at the two ends of the gravity eccentricity measurement exploring tube in an assisted mode to rotate without hindrance, so that the gravity eccentricity measurement exploring tube can be kept in the vertical direction all the time when drilling track measurement while drilling and top and bottom plate directional detection are carried out in an underground coal mine, and finally, the whole coal seam drilling track and coal seam top and bottom plate directional detection is realized.
Description
technical field [0001] The invention belongs to the technical field of measuring instruments while drilling underground in coal mines, and relates to a directional measuring probe tube and directional detection equipment for roof and floor plates under the action of gravity. Background technique [0002] At present, in underground coal mine roof and floor detection along the coal seam, most of them adopt drilling in the coal seam to detect the roof and floor in an all-round way. This method has the disadvantage of non-directional detection for the detection of the roof and floor along the coal seam. There is a lot of ambiguity in determining the position of the roof and floor in post-processing. Contents of the invention [0003] In order to solve the deficiencies in the above-mentioned background technology, the present invention provides a directional measurement probe and directional detection equipment based on the action of gravity on the roof and floor, so as to solv...
