Storage device for tunnel seismic prediction (TSP) blast hole emulsion explosive and operating method of storage device

Abstract

The invention relates to a storage device for a tunnel seismic prediction (TSP) blast hole emulsion explosive and an operating method of the storage device. The storage device comprises a stainless steel protective outer cylinder, wherein the front end of the stainless steel protective outer cylinder is provided with a clamping groove and connected with a cone spacer through a connecting piece, and a sealed conical surface can be formed when the cone spacer is closed; a hand lever is arranged at the rear end of the stainless steel protective outer cylinder. An inner cylinder is arranged in the protective outer cylinder in a sleeved mode and used for storing the emulsion explosive. An internal protruding clamping head is arranged at the front end of the inner cylinder, a hand lever is arranged at the rear end of the inner cylinder, and an external protruding clamping head is arranged in the middle of the exterior of the hand lever. An explosion blocking push rod is arranged in the inner cylinder in a sleeved mode, the emulsion explosive and an electronic detonator are protected by the rigid outer cylinder when the front end of the outer cylinder is closed, and thus the situation that the explosive is damaged by gravel and silt in a blast hole in the explosive filling process can be avoided; meanwhile, a conic shape is formed when the spacer at the front end of the outer cylinder is closed so that the device can be pushed in the blast hole easily, and the success rate of TSP blast hole detonation is increased; furthermore, the device is simple in structure and convenient to operate, the explosive can be placed to a predetermined depth of the blast hole only by continuously pulling out the inner cylinder in the outer cylinder, and the TSP blast hole explosive storage efficiency is greatly improved.

Description

technical field [0001] The invention relates to a placement device and an operation method for emulsified explosives of TSP blastholes. Background technique [0002] Tunnel Seismic Prediction, TSP for short, refers to designing and arranging a series of detection blastholes within a certain range of the side wall near the tunnel face, using a small amount of explosives to excite and generate seismic waves, and the generated seismic waves are in the form of spherical waves The form propagates in the surrounding rock of the tunnel. When the wave impedance of the surrounding rock changes (for example, when encountering a fault, a broken zone or a boundary between rock formations), part of the seismic wave will be reflected back, and the other part of the seismic wave will continue to propagate in the medium ahead. The reflected seismic wave is received by a high-precision receiver and then the data is processed by corresponding software. According to the data processing results...

Problems solved by technology

However, during the implementation of the TSP method, when the dissolution phenomenon is relatively obvious and the rock mass is relatively broken, the detection blast holes used to place the TSP explosives are prone to be blocked by mud and gravel, so that the explosives cannot enter the blast holes at the predetermined depth. Or hit the gravel on the hole wall to cause damage, affect the detonation effect, reduce the accuracy of the advanced geological prediction results, lead to delays in the construction period or cause engineering accidents
