改进Verhulst模型与灰色效果测度的软岩巷道顶板破坏规律分析
Improved Verhulst model and gray effect measure of soft rock roof failure pattern analysis
摘要
Abstract
In order to effectively predict soft rock roadway roof displacement, prevent the roof displacement and roadway destruction that brings about loss, the improved Verhulst model and gray effect measure theory were used to analyse the destruction rules of soft rock roadway roof. The displacement monitoring method was used to monitor displacement of part mine roadway, roof displacement monitoring and prediction Improved Verhulst model whose accuracy is higher was used to analyse the results, the finally displacement was gotten, and the roadway destruction was judged. The roof displacement influence factors such as roof ground stress, surrounding rock quality, road span and support pattern were applied to gray comprehensive measurement, the measurement results were combined to roadway destruction, and macroscopic stability evaluation result of mine roadway roof was gotten, when the comprehensive gray effect measure value of roadway roof is between 0-0.705 1, the roadway is stable, which provides basis for roadway design of secondary support.关键词
