Groundwater Monitoring And Early Warning System Research For Mining

At present,the frequent occurrence of mine disaster,makes people speed up on the mine disaster monitoring and early warning systems.However,technology is not greater develop,for example;monitoring system is mainly used for mining the ore body deformation and stress monitoring.In some areas,the information of mine construction is only for gas or other hazardous gas monitoring and early warning.Sudden gushing underground mine water is one of the major disasters,but the mining of groundwater monitoring and early warning is still in its infancy stage as regards to the construction and application of theoretical and methodological shortcomings.In this work,the current research is related systems for early warning systems for hydro-meteorological mine building as a useful exploration,in order to automatically obtain the hydro-geological monitoring data provided technical methods.This research work task Making Iron Mine in Longyan City,Fujian Province as an example. It is based on the Making Iron Mine hydro-geological background information and historical data, and using the database management system as the core,combined with modern means of computer monitoring,establish a groundwater monitoring and early warning systems in Making Iron Mine. It gives out architecture and ideas with a computer monitoring data detection system,through detailed analysis,combined with software engineering theory,detail-oriented monitoring hydro-meteorological data,especially for ground water level monitoring and early warning mutation prediction.The user needs to complete the function,although there may be some inadequacies,but as an exploration and application of technology,the thesis for the mine hydro-geological data automatically monitoring and information management is still of great significance.My research work mainly focus on the problems,the use of advanced technology, combination with GPRS wireless communications networks and computer programming technology,based on Visual C++,VBA and SQL Server 2000 software to develop programmes,mining of groundwater in order to achieve water monitoring and early warning systems for data management and professional analysis of the mining area for professional users and managers to provide accurate and timely monitoring data and early warning,to improve the management efficiency for decision-making managers.In this work,the mining of groundwater monitoring and early warning systems for the main study are as follows:1) Completion of the rainfall monitoring equipment,surface water monitoring equipment, as well as groundwater monitoring equipment,data integration,two different database query and operation of unification.2) Completion of the rainfall monitoring equipment,surface water monitoring equipment and groundwater monitoring equipment query basic information,including monitoring equipment position information and voltage information,and output and print statements.3) Completion of the rainfall monitoring equipment,surface water monitoring equipment, as well as groundwater monitoring equipment,data query and data to monitor the statements and line graph and print the output to facilitate analysis and monitoring.4) Completion of the precipitation,surface water level or discharge data and groundwater level at the same time inquiries,to complete the comparative analysis of their changes,and able to monitor the data output statements and line graph and print.5) Completion of the real-time monitoring of ground water level monitoring,and reporting and monitoring data to be displayed at the same time line chart,and data to monitor the statements and line chart output and printing,to facilitate monitoring.6) Completion of the data of ground water level contour map of the function,according to the study area impermeable boundary conditions,the contour map of the region limited to,the use of kriging interpolation,the completion of the ground water level contour map,and contour lines can be drawn in different base maps(topographic map,remote sensing map and geological map) and can put out and print graphics.7) Completion of the real-time monitoring of ground water level monitoring,and professional needs,according to the level of ground water monitoring data,for different set of ground water level monitoring site mutation threshold level to achieve real-time early warning mutation reminds mine security staff dealt with promptly.This is based on VC++,SQL2000 and SURFER groundwater monitoring and early warning systems for mining,using the core of development methods,the application interfaces, development environment,the underlying technologies such as database access.In the design of the database system,the system database for the sharing,system upgrades,analysis of data and applications,providing a reference template.Study of the system,proceeds from reality,and makes full use of historical data,combined with previous work,but also consider the system upgrades and maintenance,from the structural point of view has the following characteristics:1) System integration:System as far as possible,the use of the existing monitoring sites and drilling,making full use of existing resources,combined with the characteristics of the database has been completed and functional data integration on two levels. 2) System open and expandabilityBased on VC++ technology to complete the development of early warning systems,with very good development and support of LAN and WAN access and inquiry;At the same time, the upgrading of the system can function to facilitate the increase in sub-modules,application modules,as well as professional database modify,access and promotion.3) System maintainabilityThe need for the database system of data maintenance,monitoring data with the increasing amount of data,data of various system functions need to be coherent,and for the maintenance of the database data can be set up by the use of the function through the maintenance of complete data,but also through database management database for data maintenance,taking into account the data maintainability.4) The characteristics of the system itselfMaking Iron Mine groundwater monitoring and early warning system for mine is a database management,query and analysis of the thematic basis of information systems.Dynamic update existing databases,dynamic curve mapping,real-time data on water level monitoring and early warning mutation,but also contains a comprehensive analysis of functional data.From the functional point of view,Making Iron Mine groundwater monitoring and early warning system for mine has:â‘ Unity:System of a timely,accurate,not only comprehensive rainfall,surface water levels and surface water discharge and groundwater level monitoring of mining,but also achieved a unified interface,managements unity,unified style operation.â‘¡Practicality:For professional users and general users,operating guide,and concise; for professional users,statistical analysis,query efficiency,especially from the heavy task to calculate water discharge by the water level and reflecting the results of scientific data and flexible set;for the management,decision support information gap,providing a convenient and intuitively electronic data;â‘¢Security:For users to log in and operation,as well as the database in different machines and multiple backup servers,with higher data security.Mining of groundwater monitoring and early warning system is based on hydro-geological knowledge,the use of modern computer technology for design and development of data processing and early warning systems,involving hydro-geological analysis,hardware settings, software system,such a variety of factors,is a more complex system project.System in the development and trial process,exposed a number of issues,some resolved in a timely manner, and some because of technical problems,not solve,will now proceed to further analysis:1) System data download function,there are some shortcomings.2) The system of data maintenance,there are some deficiencies.3) System database in order to ensure,as far as possible to maintain accuracy,missing data in the system,while the station is not yet return to normal work,the added data is not carried out the operation and user-friendly site to keep abreast of the status of work equipment to ensure real-time monitoring stations. In this research work,the main completed integration of different data,combined with hydro-geological expertise,based on the level of ground water monitoring data,to achieve early warning of ground water level mutations,the production process for the mining of process water may have timely warning of issues for the mining management from dealing with mine water inrush time decision-making time,to provide more accurate real-time monitoring data and based on the guidance of mine safety in production.
