Abstract

The invention relates to a mining while-drilling type borehole track detection method and system and a drill rod. The method comprises the following steps that 1, a posture detection device on the drill rod is triggered, and when the posture detection device is triggered, detected posture information is encoded, and elastic waves including the encoded information are transmitted and transmitted back through a reverse path of a borehole; and 2, the elastic waves including the encoded information are received, the elastic waves are analyzed, and the corresponding posture information of the drill rod is obtained. The posture detection device is arranged on the drill rod and comprises a CPU, a battery, an encoding and decoding unit, a posture detection sensor and an elastic wave transmitting module. The mining while-drilling type borehole track detection system comprises a measuring host and the drill rod. The measuring host is in drive connection with a first elastic wave receiving and transmitting module used for transmitting and receiving the elastic waves. According to the borehole depth detection method, online borehole track detection can be achieved.

Description

technical field [0001] The invention relates to a mine-used drilling-while-drilling drilling trajectory detection method, and relates to a drill pipe and a system suitable for the method. Background technique [0002] Before coal mining operations, coal mines usually carry out geological exploration to find out the geological distribution of coal seams, rocks, and water. Coal mines with gas usually need to carry out gas drainage; these operations mainly rely on driving into coal seams or rock formations. A certain number of drilled holes. The accurate measurement of the drilling trajectory and drilling depth in the coal mine is of great significance to measure the quality of the coal mine gas drainage hole and water exploration hole. At present, the existing drilling depth measurement methods in coal mines mostly use the method of manually recording the number of rods, but when there are many rods, the problems of omission and miscalculation are prone to occur. There are a...
