Practising geographical knowledge: fields, bodies and dissemination

In this article we make a case for a renewed emphasis upon some of the generic, albeit often tacit, spaces of practice that we share across our sub–disciplinary boundaries. In this we seek to emphasize the ways in which everyday actions make up the grander facades of institutional agendas, empirical projects and disciplinary schools of thought. To achieve this we trace the performance of disciplinary contours and identities across three important sites: the field, the body and the act of dissemination. There are, we will argue, significant commonalities that bind us as disciplinary practitioners in terms of how we perform within and across these sites, and indeed, how we join them up through our practices.     

松辽盆地后五家户气田沉积相特征与控气作用

本文对松辽盆地东南部后五家户气田划分出22种沉积微相,建立7种相层序,分析了扇三角洲及三角洲沉积环境对天然气成藏的控制作用。指出了扇三角洲前缘砂体和三角洲前缘砂体较为发育,沉积物源来自气田东北部和东南部两个方向。后五家户气田多为构造—岩性气藏和岩性气藏。     

油房西矿区地球物理特征及找矿标志

油房西矿区位于华北地台北缘，苇塘河断裂西部，具有良好的银多金属找矿前景。通过对油房西矿区物性参数及局部异常特征的分析研究，探讨激电异常与矿体的关系，总结该区找矿标志，指出进一步找矿方向，以期提高地质找矿效果。     

热害矿井巷道温度场分布规律研究

为解决深部开采带来的热害问题，基于地质学和热力学理论，建立了热害矿井巷道温度场的数学模型，研究了巷道内部温度场随埋深和通风热速的变化规律。计算结果表明，巷道温度场对埋深的敏感度要高于风速、温度随埋深的增加而呈阶段性递增。控制入口温度是解决矿井热害的关键。以上结论为矿井热害的综合治理提供了重要依据。
