System and method for achieving real-time positioning of mining blasting point on shallow layer earth surface

Abstract

The invention relates to a system and method for achieving real-time positioning of a mining blasting point on a shallow layer earth surface. The method comprises the steps that a plurality of three-axis acceleration sensors are arranged on the shallow layer earth surface with the depth of 20-100 m, and the three-axis acceleration sensors pick up all blasting signals in the mining process, carry out primary filtering and signal amplification, and then output the signals; waveform characteristic analysis is carried out on the blasting signals, complete mining blasting shock waveforms are extracted, and the blasting energy, waveform information and blasting orientation information are collected and calculated; the blasting energy, blasting shock waves and blasting signal orientation are comprehensively analyzed, the optimal wave speed is automatically calculated through a waveform automatic optimizing program, the wave arrival moment is precisely extracted, and the space coordinates of a blasting point are determined with an unbalance filter algorithm and a time difference and direction combined positioning algorithm; the space coordinates of the blasting point are transmitted to a monitoring and early warning server through GPRS communication, blasting three-dimensional simulation is carried out on a monitoring and early warning platform, and early warning is carried out on layer-exceeding and boundary-exceeding information.

Description

technical field [0001] The invention relates to a system and method for real-time positioning of mining blasting points on the shallow ground surface. Background technique [0002] The supervision of mining behaviors that exceed the boundary of underground mines has always been a difficult problem for mine supervision departments. Traditional supervision uses manual or contact technical means (such as video surveillance, personnel positioning), and there are many human interference factors, which cannot fundamentally solve this problem. illegal exploitation. Contents of the invention [0003] In view of the above problems, the present invention provides a convenient and high-precision system and method for real-time positioning of mining blasting points on the shallow ground surface. [0004] The present invention realizes the real-time positioning system of mining blasting point on shallow ground surface, including: [0005] A shock wave pick-up device for collecting bl...
