Study On The Application Of ISS In The Exploration Of Structures In Coal Seams

At the present stage,the shallow coal resources in our country will be in the state of being fully exploited,many coal mines have entered the deep mining model,meanwhile,most of the large and medium-sized coal mines in China adopt mechanized mining mode with the continuous development of coal mining technology,the production of coal resources in China naturally entered the new normal of deep mechanized mining.However,The structural development of deep coal seam is generally complicated,these structures are mainly faults,folds,magmatic intrusion zone,collapse column,ancient river bed erosion zone,etc,not only the coal resource mining technology requirements are high,can not achieve the maximum resource extraction,coal and gas outburst accident,flood disaster,a series of safety problems of roof accidents and the structure caused by increasing,especially the safety problems caused by some hidden geological structures are especially prominent.If we can accurately predict the development of the internal structure of the underground coal seam,coal mine production technology department can be targeted to do technical solutions,ensuring the maximum coal mining,while ensuring the safety of the production process,to prevent the occurrence of safety accidents.ISS technology has developed and progressed after several years,Many domestic and foreign research institutes,manufacturers of continuous efforts and innovation,It is very effective to detect the internal structure of coal mine,also provide reliable technical basis for safe and efficient coal mining.This paper introduces the current situation of the development of seismic exploration technology and equipment at home and abroad,the rapid development and practicability of the current domestic seismic exploration technology and equipment are fully affirmed;the theoretical basis of the ISS is expounded;this paper introduces two successful application cases of the technology in coal mine underground structure exploration combined with the theoretical basis,the accuracy and practicability of the technique of ISS in the exploration of the internal structure of coal seam,the change of coal seam thickness,the erosion zone of the ancient river bed and the distribution of the gangue.the application case through the perspective of ISS exploration work surface internal structure and thickness of coal seams that iss in the perspective of reliability and accuracy of the internal structure of face detection,and can be used to assess the thickness of coal seam,provide the technical basis for the production of coal mine,ensure safe and efficient mining working face.Help application case of internal structure of coal seam through trough wave reflection method in exploration of coal roadway side proved that the development of the technology in the coal roadway side coal structure,coal mine construction management,working face layout to provide strong technical information.In addition,through the case by switching to the inherent detector bolt receiving new pattern,and collected the channel wave seismic information is reliable,have a reliable detection effect,to show the usefulness of the receiving mode of the time and effort.
