Description

technical field [0001] The invention relates to an integrated device and method for tsp blasthole measurement and charging. Background technique [0002] TSP (Tunnel Seismic Prediction ahead) method, that is, earthquake prediction in front of the tunnel or advanced geological prediction, refers to the arrangement of excitation holes within a certain range of the side wall near the tunnel face, and artificially stimulates seismic waves in the holes, and the generated seismic waves are in the form of spherical waves. When the wave impedance of the surrounding rock changes (such as encountering karst, fault or rock formation interface), part of the seismic wave will be reflected back, and the other part of the seismic wave will continue to propagate forward. The reflected seismic waves are received by high-precision receivers and transmitted to the host computer to form seismic wave records.

Problems solved by technology

[0003] However, in the process of TSP prediction, it is necessary to measure parameters such as the depth, inclination, and spacing of blastholes. Due to the large number of measurement items, the devices used in the measurement process are relatively complicated, and some measurement items lack accuracy.

[0004] For example, the measurement of the depth of the blast hole is mostly carried out by infrared range finder. However, due to the blocking of the hole by silt and gravel, the light of the range finder cannot be parallel to the blast hole, etc., it is difficult to accurately measure the depth of the blast hole, and the range finder is used. The measurement of the distance between the blast hole and the distance between the blast hole and the ground often has certain errors due to reasons such as non-horizontal and non-vertical

[0005] During the filling process of explosives, the emulsified explosives cannot be delivered to the bottom of the blasthole due to the inconsistency between the emulsified explosive migration path and the inclination angle of the blasthole, and the gap between the initial support of the tunnel and the surrounding rock, which eventually leads to inaccurate prediction results.

[0006] At the same time, in the existing technology, it is necessary to complete the measurement of data such as hole depth, hole spacing, and hole inclination angle according to different devices, and then use explosives filling equipment to fill the explosives into the blast holes, which is relatively inefficient.
