煤层底板突水评价的新型实用方法Ⅲ——基于GIS的ANN型脆弱性指数法应用
|
摘要
为解决我国煤矿区普遍面临的煤层底板突水评价难题,在煤层底板突水主控指标体系和脆弱性指数法提出的基础上,以邢台章村煤矿三井的9煤层开采为例,通过将新提出的基于GIS的ANN型脆弱性指数法与传统的突水系数法的评价结果进行详细对比和拟合分析,证明脆弱性指数法在煤层底板突水脆弱性评价的许多方面具有明显的优势,妥善地解决了脆弱性指数法在生产实际应用中的问题.
In order to solve the difficult problem of coal seam floor water bursting evaluation,which is widely existing in the Chinese coalfield,on the basis of the establishment of the main controlling index system of the floor water bursting and theory of the vulnerability index method,took No.9 coal seam of Zhangcun coal mine in Xingtai as an applicational example,and it proves that the vulnerability index method has obvious advantages in many aspects on the floor water bursting evaluation,and solves the problems in its practical application properly,with making detailed contrasts and fitting analogy of the results,which are evaluated respectively by the newly proposed ANN vulnerable index method based on GIS and the traditional water bursting coefficient method.
