摘要
文中首先阐述了边采边复技术的概念及基本原理,从开采沉陷学的机理出发,分析了地下煤炭开采过程中影响地面表土剥离的各种因素。将地下开采划分为若干个单元,基于概率积分法确定了各个地下开采单元对应的地面表土剥离范围及时间的计算模型,并将模型运用于山东某矿工作面,探究了其实际应用可行性。为采煤沉陷地边采边复关键技术进一步研发和推广应用提供了借鉴。
In the paper,the author elaborates the concepts and fundamentals of concurrent mining and reclamation(CMR),analyzes factors that impact soil stripping in mining advance underground,based on the mechanism of mining subsidence,and divides the underground mining into a number of units,determines the calculation model of various underground mining unit corresponding to the ground topsoil stripping scope and timing based on probability integration method(PIM).The model is applied in a panel in Shandong Province to explore the feasibility of its practical application.The research provides reference for the further development of CMR technology.
