【摘要】 论文针对开采沉陷预计参数与角量参数分类的关键问题进行了研究。首先,把开采沉陷工程问题概化为具有开挖孔洞的均质各向同性岩体的平面应变问题,建立倾斜煤层开采稳定后岩体的力学模型,根据基本力学方程和边界条件,利用相似理论方程分析法推导出开采沉陷的相似指标和相似准则,并得出开采沉陷现象移动垂直位移、水平位移和水平变形的准则关系式。其次,根据各预计参数和角量参数的定义,得出简化的预计参数和角量参数的准则关系式及其相似指标。最后,利用模糊数学聚类分析法把全国297个观测站划分为四个相似现象群(观测站)类型,给出不同群类情况下参数的取值范围,建立了每一相似现象群预计参数和角量参数的∏准则关系式的走向、上山、下山方向函数模型。通过对开滦矿区、徐州某矿和某新矿三个实例分析,提出各矿岩移参数调整的依据,验证了基于相似理论∏准则的函数模型的可靠性、适用性。更多还原

【Abstract】 This dissertation discusses the key problems with classification of mining subsidence prediction parameters and angular parameters. Firstly, the mining subsidence engineering problems are generalized as plane strain ones with homogeneous isotropic rock mass of excavation, through which mechanical model of inclined coal seam mining is established. According to the basic mechanics equations and boundary conditions, it deduces the similarity criterions and similarity criterions of mining subsidence by applying analysis method of similarity theory equation, and leads to criterion equation of vertical displacement,horizontal displacement and horizontal deformation on mining subsidence phenomenon. Secondly, following the definition of each prediction parameter and angular parameter, the simplified criterion equation and similar index of that are concluded. Finally, based on the actual materials, 297 national observation stations are divided into four similar phenomenon groups through fuzzy mathematic clustering analysis. The value ranges of the parameters under different groups and kinds are given to build function models in directions of trend, up and diphead with∏criterion equation for each similar phenomenon group’s prediction parameters and angular parameters. Taking Kailuan and Xuzhou mining lots as the analysis examples, it puts forward to the adjustment basis for each lot’s rock movement parameters, from which the function model based on the similarity theory∏standards is proved reliable and suitable.更多还原
