Study On The Construction And Application Of Synergistic Flood Prevention And Control System

As a fast and efficient detection means,the transient electromagnetic method plays a vital role in the waterproofing prediction of shaft and tunnel.Considering the wholespace effect,the data of each transient electromagnetic detection measuring point is actually the comprehensive reflection of geologic body ahead of the tunnel and behind the roadway.Based on this point,the effects of the transient electromagnetic response of the low resistance body in tunnel's sides,considering the electrical conductivity,the position and the volume are analyzed through forward modeling.According to the above analysis,the whole-space effect as well as the current research status of transient electromagnetic three-dimensional inversion,it is difficult to remove quickly and efficiently the interference information from the low resistance body in tunnel's sides by theoretical analysis.Therefore,this paper uses multi-data cross analysis to reduce the interference of the proven low-resistance body.The multi-data existing in various decentralized and relatively independent systems and departments are sorted: regional Geological data,hydrological data,engineering roadway data,ventilation data,electromechanical data and geophysical data.However,the cooperative analysis of multi-data is difficult under the current situation of mining information development.So,this paper established the framework of synergistic flood prevention and control system through analyzing its basic connotation,objective,object and content.What's more,an information platform for synergistic flood prevention and control was developed.Through the method of hierarchical management of data,the coordination and crossover analysis of water damage control data is realized,and the field test is successfully carried out in Shengping coal mine.The synergistic flood prevention and control platform can not only integrate and co-analyze various flood prevention data,study the water damage distribution and water intrusion laws and guide the safety production of the mine,but also provide a data basis for the research of the next mining large data analysis?The main research results obtained in this paper are as follows:(1)The influence of roadway side resistance on transient electromagnetic response of front low resistance body is studied,and the feasibility of the three dimensional inversion of the transient electromagnetic field is analyzed.(2)The basic connotation,objectives,objects,contents and characteristics of synergistic flood prevention and control system were analyzed,and a synergistic flood prevention and control system was constructed.(3)Based on the synergistic flood prevention and control system,the information platform for synergistic flood prevention and control was developed and field tests were carried out in Shengping mine.(4)Using synergistic flood prevention and control information platform,seven consecutive transient electromagnetic advanced detection were carried out on the 2202 working face of the Shengping coal mine,and the data of transient electromagnetic detection and geological data were cross-analyzed by using the platform.The results of the analysis are verified by drilling,and it is proved that the method can effectively weaken the influence of the existing low resistance body.
