Key Technologies On "One-chart" Construction In Coal Mining Area

In recent years, Departments of land and resources have been promoting the project of ?One Map'of the whole country actively to realize the whole cover and flow dynamic monitoring of the land and mineral resources and to achieve managing the land and mine with one map. It has been proved that this is vital to the harmony of land utilization and coal resource exploitation and harmonizing resource exploitation with environment conservation. However, there are also many problems.Based on multidisciplinary theories and research methods, this paper discusses several key technological questions on the information obtainment and the development and application of the core database and synthesize monitoring and decision-making platform, taking Qianyingzi Coal Mine, Shendong Coal Mine and Jiahe Coal Mine of Xuzhou for examples. This paper first summarizes the coal and mineral resources, land resources management problems in an integrated monitoring, analysis of the content and framework of the coal mining area "one-map" consolidated supervision; With multi-source, multi-temporal, multi-scale remote sensing data of the coal mining land use "one-map" data fusion processing and evaluation techniques, analysis feasibility of the use of remote sensing image fusion of multi-source data update 1:2000 mine large-scale topographic map, discussing the mineral development disturbance of land use / cover classification and spatial pattern dynamics monitoring technology; on this basis ,have interference processing through the SAR data achieve by different sensors (ALOS, ENVISAT synthetic aperture radar data), discussed the technical processes of D-InSAR with two-pass methods for surface subsidence monitoring, the use of timing SAR to established a mining settlement nonlinear model, revealing the temporal and spatial deformation of the surface subsidence evolution. The use of GIS, and other means of information of things, on the basis of analysis internet of things and the status quo of mining of things, studied the key technologies of underground mineral resources in coal mining areas perception of things, discussed the real-time location of a wireless technology (Wi-Fi RTLS), Custom UDP communication protocol data packet transmission and processing methods, in-depth analysis the operating principle of perception of mining GIS monitoring system (MIOTGIS),to build MIOTGIS four structural model which based on the perception layer, network layer, data layer and application layer, the design of network-aware mining ER model and database deployment. NET-based platform for the development of underground facilities and real-time positioning and historical trajectory of representation functions, to achieve the extraction of mineral resources to track the more layer of cross-border surveillance of illegal exploitation of underground resources in the whole mining process, comprehensive long-range precision of transparent management.By combining coal mining area on the ground, surface, underground multi-source information, integrated mining land ownership, land planning, land utilization, land reclamation and other "cadastral" information and mining mineral resources, mineral resources planning, mineral reserves, state of mineral development and other "mineral origin" information, analysis of the physical elements of classification coding and the construction in two data centers of cities and counties, enabling a coal mining area of land and mineral resources, "one-map" of the unified data organization, the establishment of the mine to "one-map "core database to achieve data integration, storage tiering, centralized management, distributed applications. At the same time, based on computer networks and hardware, combination dual architecture model of B / S and C / S, the construction of the GIS system as a platform to rely on a set of Web technology for land, mineral policy, decision analysis in one coal mining area, "one-map" comprehensive regulatory decision-making platform, to achieve the mining and mineral resources, land resources monitoring and management of macroeconomic policy-making.
