综放沿空掘巷围岩稳定性分类模型及应用

朱川曲,王卫军,施式亮

《中国工程科学》 2006年第8卷第3期页码 35-38

摘要：

讨论了综放沿空掘巷围岩的稳定性，并根据理论分析、实践经验和现场观测数据的整理分析，构造了综放沿空掘巷围岩稳定性影响因素的隶属函数，建立了灰色-模糊分类模型；实际应用表明，该模型准确、可靠，对于综放沿空掘巷的支护设计、施工和管理具有指导作用。

风流脉动下采空区流场数值模拟与实验研究

李永存,林爱晖,王海桥,刘荣华

《中国工程科学》 2008年第10卷第2期页码 41-45

摘要：

针对矿井内风流脉动的特性，基于矿井通风理论、流体力学理论、空气动力学理论、传热传质学理论、多孔介质渗流理论，建立了矿井风流脉动下采空区流场的计算模型；通过数值模拟，研究了脉动风流作用下采空区流场的分布特点，并通过实验对其进行了测试和验证。结果表明所建立的采空区非稳定流场的数学模型可用于研究采空区流场分布状态，并为采空区火灾防治提供有效的手段。

Model test of the group piles foundation of a high-speed railway bridge in mined-out area

Xin LIANG,Qian-gong CHENG,Jiu-jiang WU,Jian-ming CHEN

《结构与土木工程前沿（英文）》 2016年第10卷第4期页码 488-498 doi: 10.1007/s11709-016-0338-x

摘要： The research on the mechanism of pile-soil-cap-goaf interaction and settlement of high-speed railway bridge located in mined-out area is still relatively rare. By taking the pile group of Guanshandi bridge foundation in Hefei-Fuzhou high-speed railway as the prototype, a model test is carried out. According to the similarity theory, the similar constant is derived and the similar model material is determined. Meanwhile, three types of data including the bearing behavior of piles, and the settlement law, and soil among piles are investigated. It can be found that: the influence of goaf on the bearing capacity of pile is inversely to the loading degree, the larger of loading degree, the smaller impact of goaf on the bearing capacity. There is no negative side friction can been found in pile body and the degree of downward tendency for the barycenter of side friction layout is obvious for piles in goaf. Although the bearing ratio of soil resistance under cap is relatively large, the cap effect is suggested be ignored considering the characteristic of goaf. There is a maximum critical value for the uneven settlement of pile group in goaf, and when the value is reached, the uneven settlement stop growing anymore. In addition, the formula for calculating bearing capacity and settlement of pile group in goaf based on test results, theory analysis and related standard is established.

广域电磁法和拟流场法精细探测技术——以井工一矿水害探测为例 Article

何继善

《工程（英文）》 2018年第4卷第5期页码 667-675 doi: 10.1016/j.eng.2018.09.006

摘要：

井工一矿存在严重的老空区和水害。以往的单一勘探方法，如地震法、直流电法、音频大地电磁法、可控源音频大地电磁法、瞬变电磁法等，均未能探明老采空区范围和水害赋存情况。为了解决这个难题，联合采用广域电磁法和井- 地拟流场法的三位一体立体式探测技术，并利用三维反演电阻率资料精准获取富水区域和采空区的位置，确定了不同层位水的连通性，为井工一矿的安全生产提供了可靠的技术保障。结果合理、成效显著，释放了近4 km² 的可采面积。
