Embodiment Construction

[0022] The installation device of the deep hole microseismic monitoring sensor in the mine includes the installation mechanism formed by connecting the anchor fluke 2, the upper connecting rod 3, the geophone 13, and the lower connecting rod 15. The lower end of the anchor fluke 2 and the upper connecting rod 3 are connected by threads, The upper connecting rod 3 and the detector 13 are connected by threads, and the detector 13 and the lower connecting rod 15 are connected by threads. The outer installation bag 4 and the inner installation bag 5 are fixed between the first support ring 11 and the second support ring 7 with the upper binding belt 10 and the lower binding belt 6 respectively. The lower end of the anchor fluke 2 is processed with internal threads; the two ends of the upper connecting rod 3 are processed with external threads, and the first support ring 11 is welded at its upper end; the two ends of the detector 13 are processed with internal threads; the lower con...

Abstract

The invention discloses an under-mine deep hole microseism monitoring sensor mounting device, which comprises a mounting mechanism formed by connecting an anchor jaw, an upper connecting rod, a wave detector and a lower connecting rod, wherein the anchor jaw, the upper connecting rod, the wave detector and the lower connecting rod are connected with one another through threads; an outer mounting bag and an inner mounting bag are fixed between a first supporting ring and a second supporting ring through banding strips respectively; the under-mine deep hole microseism monitoring sensor mounting device is pushed into the bottom of a drill hole by a mounting rod and a mounting rod joint in the mounting process step by step, and an operation rope is pulled in the reverse direction of a mounting direction, so that the wave detector is completely coated by cement paste; and the mounting rod is pull out of the drill hole step by step to finish the mounting process. By the mounting device, the defects that a lifting rope is easy to wind, the anchor jaw is easy to slide downwards, a sensor is inconvenient to mount and the like in the conventional mounting method are overcome; and the device can be popularized and applied in microseism monitoring processes of mines, water conservancy projects, side slope projects and tunneling projects.

Description

technical field [0001] The invention relates to underground safety monitoring of coal mines, in particular to a sensor installation device in the field of microseismic monitoring. Background technique [0002] Microseismic monitoring technology is a multidisciplinary interdisciplinary technology involving mining, geophysics, computer technology, and communication technology. It has been gradually applied to the monitoring and early warning of mine dynamic disasters this year. The microseismic monitoring sensor is an important part of the microseismic monitoring system, which has the function of receiving shock waves. At present, when the installation depth of the microseismic monitoring sensor is relatively shallow (450m), the ground is generally drilled downwards, and then the microseismic monitoring sensor is installed at the bottom of the borehole by casting method. This method of ground drilling cannot be used in deep mines (greater than 450m), and the cost is relativel...
