Multifunctional measuring instrument for seismic-wave-method advance geological forecast and application method thereof

The invention relates to a multifunctional measuring instrument for seismic-wave-method advance geological forecast. The multifunctional measuring instrument comprises a body and a laser detection rod, wherein the laser detection rod can be rotated in all directions and a laser detection head is arranged at one end of the laser detection rod; the body is internally provided with an angle measurement system, a laser range measuring system and a USB (Universal Serial Bus) interface; the angle measurement system is connected with the detection rod by a groove and can be used for directly reading out an inclined angle; the laser range measuring system can be used for measuring a distance between any two points through a control circuit and the data can be transmitted by the USB interface. The device integrates blasting hole inclined angle measurement, blasting hole depth measurement, measurement of a distance from a blasting hole to the ground, measurement of a distance from the blasting hole to a tunnel face, and data transmission; meanwhile, the invention further discloses an application method of the device. The device has a simple structure and is easy to operate; the detection time of the advance geological forecast can be greatly shortened and the detection working efficiency is improved.
