Currently, the frequent occurrence of the mine, causing people to accelerate the construction of the mine disaster monitoring and early warning systems. The mine disaster monitoring and early warning system is mainly used for the mine's ore body deformation and in situ stress monitoring, and in some areas only for gas or other hazardous gas monitoring and early warning. Underground water gushing sudden water is one of the major disasters of the mine, but mine groundwater monitoring and early warning is still in its infancy stage, there are a lack of theory and methods in system construction and application. This paper studies the status quo of China's current monitoring system, made a useful exploration for the construction of the mine hydro-meteorological early warning system and provide technical methods to automatically obtain hydrogeological monitoring data. The paper selected Longyan City, Fujian Province, Ma Hang iron ore, for example mine hydrogeological background information and historical data, as the core database management system, combined with modern monitoring techniques and methods, initially established a the Ma Hang iron ore groundwater monitoring and early warning systems, systems architecture and construction ideas; through a detailed needs analysis, combined with software engineering theory, elaborated monitoring of hydrological and meteorological data. Especially targeted mutation of the groundwater level monitoring and early warning, to complete the system. Although the system has some shortcomings, but as a technical exploration and mine hydrogeological data automatically monitoring and information management is still of great significance. This article is mainly for special monitoring of the mine hydrology, using the GPRS wireless communication networks and computer programming techniques, software development based on Visual C, VBA and SQL Server, and the mine groundwater monitoring and early warning systems, and complete data management and professional analysis functions for the professional user and mine managers to provide accurate and timely monitoring data. Of the groundwater occurring mutations warning to improve the efficiency of the manager's decision-making. The system mainly consists of the following functions: 1) complete monitoring of precipitation, surface water monitoring, and monitoring of the groundwater monitoring database data integration, unified monitoring database queries and operations; 2) of rainfall monitoring equipment, surface water monitoring equipment, and groundwater monitoring equipment information query capabilities, including monitoring site equipment location information and the voltage information; 3) completion of monitoring of precipitation, surface water, groundwater monitoring data query capabilities; 4) the completion of the rainfall The amount of water level or water of surface water and groundwater level data while query calculation and comparative analysis; 5) to complete the real-time monitoring of groundwater levels and monitoring data reports, and line charts are displayed at the same time; 6) completed groundwater level data, contour drawing, impermeable boundary conditions of the mine, the area was limited contour drawing, using kriging interpolation, the completion of the groundwater level contour drawing, and these contours draw on different base maps (topographic maps, remote sensing map and geological map); 7) the real-time monitoring of the groundwater system and early warning capabilities, based on the groundwater level monitoring data, groundwater level set of different monitoring sites mutation threshold to achieve water level mutations in real-time early warning, to remind mine safety staff processed in a timely manner. The above query and monitoring data are output reports and graphics, user-friendly analysis and application. Based Vc, SQL Server 2000 and Surfer developed mine groundwater monitoring and early warning systems, core developers, in strict accordance with the theory of software engineering design and development. System to achieve functional analysis in the design of the database, the sharing of the system database, system upgrades, data and application to provide a reference template. Study of the system, from the reality, and make full use of historical data, combined with the early work, take full account of system upgrades and maintenance, its structure has the following characteristics: 1) the integration of the system as much as possible the use of existing monitoring sites and drilling, make full use of existing resources and combine the characteristics of an existing database, completed the two levels of data and functional integration. 2) system openness and scalability complete VC technology-based early warning system development, support for LAN and WAN access and query; system upgrade at the same time, you can easily increase the functional sub-modules, specialized application modules as well as changes to the database access and upgrade. 3) easy maintenance monitoring of data continues to increase, for the maintenance of the database data is a problem, the maintenance can be done by the user, but also may be completed by the database management, to ensure the maintainability of the data. 4) the characteristics of the system itself mine groundwater monitoring and early warning system is a set of database management, the thematic query and fundamental analysis information systems, including database updates, data real-time monitoring and the water level mutations warning, and also includes a comprehensive analysis of the data The function of the system to ensure the unity, practicality and safety. ① unity: timely, accurate, comprehensive mine rainfall, surface water level and surface water flow, groundwater level monitoring, also implements interface is unified, unified management, unified operating style; ② practicality: For professional users ordinary users, operating wizard concise; For professional users with high query efficiency and statistical analysis, in particular, is exempt from the heavy the sectional flow calculation work embodies the scientific data and results and flexible set; management department for the management decision-making, and provides a convenient and intuitive electronic data; ③ security: higher data security for user login and operation, as well as the multiple backups of the database on a different machine and server. The the mine groundwater monitoring and early warning system is based on knowledge of hydrogeology, the use of modern computer technology to design and development of data processing and early warning systems involving hydrogeological expert analysis, computer hardware and software systems development is a complex system engineering. System exposed some problems in the process of development and trial, and some timely solutions to some is temporarily unavailable because of technical problems to solve: 1) data download function, there are some defects; 2) system data maintenance, there is a certain inadequate; 3) In order to ensure the system database maintained as much as possible correctness, is missing in the system data, and the Stations not resume normal working conditions, the complementary operation of the data is not performed, user timely understanding of the device site the working conditions, to ensure that the real-time monitoring of the monitoring stations.
