矿区专用铁路开采沉陷预计及治理系统研究

Study on the Forecasting and Maintenance System of Special Railway Subsidence in Mine Area

在矿区铁路下进行放顶煤开采所引起的地表及铁路的变形量大,变形速度快,从而导致矿区铁路维护困难。如果在开采前及开采过程中对地表及铁路的变形预计不准确,维修措施不当,将无法保证矿区铁路的正常运输,甚至出现安全行车事故。为此,研究开发了综采放顶煤条件下铁路开采沉陷预计及其治理系统,该系统通过对地表及铁路的变形进行较为准确的预计,可提出铁路线路及道岔的维修治理措施。

The fully mechanized caving coal mining under the railway in mine area will result in difficult maintenance of railway because of great deformation and subsidence speed of terrene and railway. If the deformation forecasting of terrene and railwayis incorrect and maintenance measure is not suitable in the preceding and the process of mining, the normal operation of the railway in mine area will not be ensured and perhaps the safety accident will take place. Therefore, the railway subsidence forecasting and maintenance system for fully mechanized coal caving was studied and developed. Based on the accurate deformation and subsidence forecasting of the terrene and railway, the maintenance measure for track and switch turnout in railway is put forward in this system.
