为了解决底板突水预测预报评价的难题,在建立煤层底板突水主控指标基础上,采用端点三角白化权函数和中心点三角白化权函数灰色评价对矿区某一小块进行评价,并通过比较得出中心点白化权函数灰色评价的结果更可靠。运用中心点白化权函数对古汉山矿底板突水危险性进行灰色评价分析,得出底板突水危险性分布图,同时对底板突水危险性趋势进行了预测。

英文摘要：

In order to solve the problem in prediction evaluation of water inrush from coal seam floor, based on theestablishment of the main control indexes of floor water inrush, evaluation was conducted on a small block of the mining area byusing the grey evaluation of the endpoint triangle whitening weight function and center point triangle whitening weight function,and through the comparison, it was concluded that the grey evaluation results of the center point whitening weight function weremore reliable. Grey evaluation and analysis were carried out on the floor water inrush hazard in Guhanshan Mine by using thecenter point whitening weight function, and the distribution of floor water inrush hazard was thus obtained. In addition,prediction was made on the tendency of floor water inrush hazard.
