华北型煤田矿坑突水因素的信息分析

矿坑突水以其突发性的特点易于酿成事故，危及矿工生命和矿井安全，因此在查清煤矿床充水条件的基础上，进行矿坑交水预报特别重要。这就首先需要解决突水因素（子）的组合优化问题，以往多是从定性分析的角度进行决策分析，影响矿坑交水预测的精度，并且因人而异，操作起来特别困难。本文运用信息分析的原理和方法，借助信息分析手段，使各类交水因素对突水岩体的作用大小通过信息量这一信息单位来度量，为突水因素分析提供了一种定量分析的手段，从而解决了各类突水因素的优化和配置问题。

INFORMATION ANALYSIS ON WATER INRUSH FACTORS OF COAL MINE IN NORTH CHINA

Water inrush in coal mine area is a sudden phenomenon,which results in accidents,rnakes miner die and mine well unsafety. Being based on detecting out recharge condition,it is necessary to solve the problem of water inrush factors allocanon. At the past,it was very diffcult to decide this problem (luantitatively. We have applied the tool of information analysis,made size of water inrush factors acting on rockmass ed)ressed by relative information measure quantity as information unit.So,an effective tools is Provided for water inrush factors analysis in this paper.
