【摘要】 为了合理确定条带开采留宽长度,模拟条带开采引起的地表变形,开挖环境的工程措施要求、保护对象的空间位置和开采岩层的情况,选用相应的条带开采沉陷机理、计算模型和计算方法,用以预测设计开采区的地表变形以及采后数据整理。全部工作是在自行研发的软件包的基础上完成,实现了地表变形计算的可视化分析系统。依据马蹄沟煤矿地面观测资料及采区的地质开采条件为基础,应用该系统,指导该矿成功的在河流及建筑物下开采,做到了准确预测预报。更多还原

【Abstract】 In order to reasonably determine the mining width and reserved length of strip mining,and simulate surface deformation due to strip mining under earth,according to the requirements for engineering measures and the protected object’s space position,the mined rock strata’s circumstance the relevant mining subsidence mechanism and calculation model are chosen in order to predict the designing mining area transformation and data sorting after mining.Its function and performance are put into practice for all various aspects of subsidence calculation in visual analysis system of our own developed software package.It is applicable to all mining geological conditions and mining methods.Based on the condition of strip and pillar practice of Matigou Colliery of Huating Mining Group,this calculation system was used to guide successful mining under river and architectural complexment.Accurate estimation forecast were attained.更多还原
