Method for rapidly fixing micro-quake sensor underground

Abstract

The invention provides a method for rapidly fixing a micro-quake sensor underground. The fixing method is characterized in that on the basis that an anchor rod (11) provided by the support way of an underground coal roadway driving working surface anchor rod (11) is taken as a carrier, the conventional buried type installation way is changed, and a sensor and the anchor rod (11) are fixedly connected integrally by rapidly fixing the micro-quake sensor device underground. The device comprises an outer cover and a connector, wherein the outer cover consists of a bottom plate (2), a cover body (3), an external sound wave insulating material (4) and closing holes (5), wherein the connector consists of a protruding shaft (7), a baffle plate (8) and a fixing bolt (9). By adopting the method, a series of problems of complex installation procedures, high time consumption, difficulty recovery and the like in the conventional micro-quake sensor installation way are solved. Rapid installation and detachment of the sensor are realized. Moreover, the cover body provided by the device can be used for fixing and protecting the sensor, and plays a role in insulating and eliminating noise.

Description

technical field [0001] The invention relates to a method for rapidly fixing a microseismic sensor in a well, and relates to a method for installing a microseismic sensor in a bolt type. Background technique [0002] my country is the world's largest coal-producing country, and its coal consumption ranks first in the world. In 2000, raw coal accounted for 66.6% of my country's total primary energy production. Since 2002, the state has adjusted the energy strategy, which is summarized as "guaranteeing safety, optimizing structure, improving efficiency, protecting the environment, and expanding opening up; limited energy conservation, diversified structure, environment-friendly, and market-driven", emphasizing the diversity of energy development and During this period, coal mining has returned to the dominant position in the overall energy, and its economic status is also recovering day by day. In 2004, the National Development and Reform Commission combined with the status q...

Problems solved by technology

At present, the installation of microseismic sensors is mostly embedded, which leads to cumbersome installation process and wastes a lot of manpower and material resources, and it is difficult to recycle, resulting in huge economic losses.

In addition, the signal collected by the sensor in the traditional installation method is relatively rich, which cannot well isolate the noise influence of other external working processes
