采空区处理方法研究进展

采空区处理问题一直是国内外普遍存在的采矿技术难题。简要综述"崩"、"充"、"撑"、"封"等4类基本的采空区处理方法和4种简单联合法。认为联合法是一类最有发展前景的采空区处理方法。专门阐述几种采空区处理的新方法。提出采空区处理方法的发展方向:切合实际、经济简便、技术可行,能定量设计与分析,能消除冲击地压,能控制开采地压,能智能选择,其发展应以围岩应力和变形仿真为核心。

Progress in Developing Methods for Dealing with Forsaken Stope

Dealing with the anandoned stope properly has been an imperative mining problem both at home and abroad.Four kinds of basic methods for disposing abandoned-stope,i.e."caving","filling","support","isolation",and four classes of the simply united methods were all reviewed briefly.And then the united methods were considered as a kind of the most promising abandoned-stope disposal methods.Moreover,some new methods for disposing abandoned-stope were too summarized specially.A direction for developing abandoned-stope dealing with methods was put forward: the method to be developed should be made conform to the reality,economic and simple,feasible technically,able to be designed and analyzed quatitatively,able to eliminate impact pressure,able to control mining ground pressure,and able to be chosen intelligently,and the rock-mass stress and displacement simulation should be taken as the core of its development.
