Split type two-way dipmeter for hole drilling

The invention relates to a split type two-way dipmeter for hole drilling. The split type two-way dipmeter is used for country rock stress measurement or digging dynamic pressure measurement in the mine engineering and comprises a measurement main machine and an installation rod. The measurement main machine is arranged outside a hole. The installation rod is inserted into the hole. The front end of the installation rod is connected with an installation sleeve. The front end of the installation sleeve is connected with a pressure sensor. An accelerometer base is arranged in the installation sleeve and provided with an installation groove. A small-scale triaxial accelerometer is fixed in the installation groove. The accelerometer installation face of the installation groove is parallel to the pressure sensor reference face. The small-scale triaxial accelerometer is connected with the measurement main machine through a four-core cable and an aviation plug thereof. The four-core cable penetrates through cable outlet holes in the installation rod and the accelerometer base. The split type two-way dipmeter for hole drilling is applicable to large and small hole diameters based on the corresponding relation between triaxial acceleration and the biaxial inclination angle, achieves high-precision biaxial inclination angle nearby pressure sensor measurement, provides a precision guarantee for deep hole mine pressure observation, and improves support parameter design and equipment selection scientificity and rationality.
