一、前言 本文根据突出发生的临界深度,提出了判定区域性突出危险或新建矿井突出危险的分析方法(即区域有效半径法)。事先确定某煤层或部分煤层,即新开工作面的突出危险程度,是局部预报突出危险之目的。应强调指出,世界煤炭工业中大部分预报突出的方法均具有分析的特点。往往根据若干可检

I. INTRODUCTION According to the critical depth of prominent occurrence, this paper puts forward the analytical method (ie, the area effective radius method) for judging the prominent danger in the region or the prominent danger in the new mine. It is the purpose of the local forecast to highlight the danger if the certainty of a certain coal seam or part of the coal seam, that is, the prominent danger of the newly opened working face, is determined in advance. It should be emphasized that most of the methods forecasted in the forecasting of the world's coal industry are analytically characterized. Often based on a number of seizures
