煤矿立井非采动破裂工程地质勘察方法

深厚表土中煤矿立井非采动破裂是一种新的矿井地质灾害。以往的煤田地质勘探工作没有涉及该问题。本文建议立井破裂工程地质勘察可划分为初步勘察和详细勘察两阶段，提出了各阶段应包含的具体工作内容和工作方法；特别是提出要进行模拟土与井壁相互作用试验，获得不同埋深土层与井壁相互作用的力学参数；提出在勘探阶段判断厚表土层中煤矿立井非采动破裂的系统工作方法。最后给出了一勘察分析实例。

Engineering geological investigation method of non-mining rupture shaft lining of coal mine in thick deep soils

Non-mining rupture of coal mine shaft lining in thick deep soils is a new kind of mine geological disaster. There was no the same problem encountered in the past coal geological exploration. This paper suggest that the engineering geological investigation of shaft lining rupture can be divided as preliminary and detailed phases, the working contents and methods of each investigation phase is also put forward. Especially address that the test for simulating the interaction between soil and shaft wall should be carried out, by which the mechanical parameters of the interaction between varies buried soil and shaft wall can be got. A system of work method used to judge the possibility of the shaft lining rupture in geological exploration phase is put forward. Lastly, a case study is presented.
