Description

technical field [0001] The invention belongs to the technical field of goaf detection in an open-pit iron mine stope, and in particular relates to an auxiliary fixing device for a seismometer suitable for an open-pit iron mine stope. Background technique [0002] In the process of mineral resource development and utilization, due to random mining and indiscriminate mining and the transformation of scattered mining into overall mining in the process of mining integration, there are many unknown goafs in and around many mines, and these unknown goafs There is no detailed geological data, and some goafs may have been filled with water and deformed, and these unknown goafs are seriously affecting the daily production of the mine, and are always threatening the safety of stope workers and equipment. Therefore, how to accurately detect gobs has become one of the security problems that open-pit iron ore stopes must face at this stage. [0003] At present, the shallow seismic imagi...

Problems solved by technology

[0004] In order to ensure the acquisition accuracy of seismic wave data, it is necessary to ensure the position stability of the seismometer after the installation is completed. Caused no small difficulty in fixing the geophone

[0005] Currently, gypsum or soil filling is usually used to fix the geophone on the surface of the hard rock base, or to drill a hole in the surface of the hard rock base, and then insert the geophone into the drilled hole to complete the fixation; however, Using the above two fixing methods, it is difficult to ensure the stability of the position between the geophone and the ground surface. During the measurement process, the geophone is easily shaken under the action of external force, which affects the data quality.

At the same time, since there is no shelter in the open-pit iron mine stope, the geophone will be exposed to sunlight for a long time, and long-term sunlight will affect the data accuracy and the life of the geophone
