铁路煤矿采空区的综合物探研究

RESEARCH ON INTEGRATED GEOPHYSICAL EXPLORATION FOR RAILWAY SURVEY IN COAL MINE GOAF

铁路采空区勘察有工期紧、精度高、勘察费用控制适度等特点,经过多年的探索研究实践,研究了各方法在目的体异常、探测深度、抗工业游散电流干扰、兼顾效果与效率等方面的优缺点,初步总结出了有效工作方法和模式,可以较好解决采空区分布范围,节省了大量的深孔,为线路方案优选和处理提供可靠的技术资料。综合物探技术已成为解决采空工程地质问题的首选技术。

The railway survey in goaf area always faces such problems as tight schedule, high accuracy and high cost. The author preliminarily summed up the effective methods and models after years of research and practice, studied the advantages and disadvantages of various kinds of geophysical methods which were used for anomaly of the object body, and the detection depth and the anti-industrial stray current interference by taking into account the effect and efficiency. These methods and models can solve the problem of the distri- bution of the goaf. A large quantity of deep drilling work can be reduced, and reliable technical information can be provided for railway line selection and processing. The integrated geophysical technology has become the preferred technology for solving the engineering, geological problems of the goaf area.
