GIS技术在煤层底板水害评价中的应用
首发时间:2017-05-13
摘要:为有效防治煤层底板水害,提高评价精度,研究提出将GIS技术应用于煤层底板水害评价中。论文以燕子山矿8号煤层底板寒灰水害评价为例,在建立基于GIS的影响煤层底板突水的隔水层厚度和水压两大因素专题层图基础上,通过叠加分析,得出煤层底板突水系数值,并进行了突水危险性评价分区。进一步将得出的评价分区与传统基于钻孔点的突水系数法评价分区相比可知,基于GIS的突水系数法评价更吻合实际。因此,GIS技术在煤层底板水害评价中的成功应用,为有效防治煤层底板水害提供了技术支持。

The Application of GIS Technology in the Evaluation of Coal Seam Floor Water Inrush
Abstract:To effectively control coal floor water inrush and improve the accuracy of evaluation, the GIS technology was proposed in the evaluation of coal floor water inrush. The evaluation of No. 8 coal seam floor Cambrian limestone water in Yanzishan mine was taken as an example. First, the two thematic maps of aquifuge thickness and water pressure affecting coal floor water inrush were established based on GIS. Then, the value of water-inrush coefficient were obtained after overlay analysis, and the result of it was divided into two types. Further, comparing the results of the evaluation based on GIS with the results of the evaluation based on the traditional drilling point, the water inrush coefficient method based on GIS is more consistent with reality. Therefore, the successful application of GIS technology in the coal floor water inrush provides technical support for effectively controlling coal seam floor water inrush.
Keywords: floor water inrush water inrush coefficient method GIS nonlinear
