Research On Cavern Planar Mapping System

The Cavern Plane is foundation of evaluation and analysis of cavern applicability, safety and stability. At present, it is still deliberating that what should be and how to be expressed on the Cavern Plane, no unified consensus. Try to design and establish Cavern planar mapping system, based on the comprehensive for Cavern Plane research situation at internal and abroad, and the information obtained from the cavern utilization enterprise in Jintan, in this paper. The system is developed by the database technology, the MFC application develop technology and the further develop of AutoCAD technology based on the ObectARX, implement the consistent and effect cavern data management, draw the cavern planar graph and the vertical profile quickly and accurately.The main contents are as follows:[1] This paper introduces what is the cavern data constitute, and how to organize and manage the cavern data, so that make it become an organic whole. The research found that the base direction of cavern and well tracing line is different with the base direction of the topographic map, and made a corresponding solution with the program.[2] A suitable for cavern data management is introduced, the module of cavern data management and the cavern database is established. The system will unify cavern data, and calculate the cavern projection profile, the largest section in the cavern and the shortest distance between two caverns with the program, and store the calculation result to the cavern database.[3] The contents of cavern planar mapping is studied, the module of cavern planar mapping system is established, the cavern planar drawing and cavern section program is realization in the AutoCAD 2012.
