摘要
本文简述了几年来在采场矿山压力研究的成果，如：作为直接顶边界条件的老顶“砌体梁”结构的形式以及如何简化此结构以及关键块分析中提到的“Ｓ－Ｒ”稳定、采场整体力学模型的建立、“支架工作阻力－顶板下沉量”双曲线的再讨论以及如何应用断裂岩块的相互作用机制分析煤矿开采后的底板突水准则等，本文也期望矿压界的科研工作者为进一步完善采场矿山压力理论的研究进行讨论。
The paper simply discussed the research results on face underground pressure recent years, such as the type of“voussoir beam”structure of main roof and its simplification, the “R-S” stability in analysis of the key block, the establishment of the mechanical model of whole coal face, rediscussion of “support working resistance- roof subsidence”, the criterion of floor water inrush by using the mechanism of interaction of fractured blocks and so on. The pape ralso hopes the research workers on underground pressure continuouslydiscuss the underground pressure theory for its further perfect.
