摘要
提出了采场上覆岩层移动的组合岩梁模型,将岩层移动的关键层、岩层组合以及层间离层统一在组合岩梁模型的体系中,建立了关键层、岩层组合以及层间离层的统一判别准则,并进行了实例分析。对组合岩梁模型在岩层移动规律研究、地表沉陷控制以及在矿井瓦斯防治中的应用进行了深入地分析。组合岩梁模型的建立,为采场矿压和岩层移动的研究提供了一种新的思想和方法。
The composed rock beam model for movement of overlying strata in stope is proposed. The key stratum of strata movement, the strata combinations of ground control and the separated bed are unified in this model, and a unitive criterion for determining the key stratum, the strata combinations and the separated bed is founded with an example analyzed. The applications of the composed rock beam model in ground control, surface subsidence control and gas prevention in coalmine are studied deeply. This model provides a unified idea and method for study of pressure in longwall mining and strata movement.
