摘要
在概率积分预计方法的基础上,通过引入开采沉陷率和拐点偏移距关于宽深比的玻兹曼函数,建立了顾及不同开采充分性的开采沉陷预计模型.为各类非充分开采(大采深煤层开采、条带开采、房柱式开采等)的岩层和地表移动计算提供了新的统一的数学模型.
On the basis of Probability Integral Prediction Method, a new subsidence model is established for the conditions of various mining extents by citing a Boltzman function to express subsidence rates and inflection point displacement about the ratio of mining wide to height. It provides a unified model for calculating strata and ground displacement and deformation induced by coal seam mining with great height, trip mining, roomandpillar mining, etc.
