| 摘 要： | H2101是我国第一个海下采煤工作面.巷道围岩属于第三系软岩,所以巷道支护难度非常大.根据岩石和围岩的蠕变机理以及软岩流变控制原则,建立龙口矿区北皂煤矿海域第三系软岩巷道围岩蠕变最优支护计算方法,求出软岩支护的两个重要参数,即最优(小) 支护力和围岩最大允许变形量,作为进行支护设计的重要参数,为解决海下安全开采提供了理论依据. |
| 关 键 词： | 软岩支护 蠕变 最优支护力 最大允许变形 围岩 |

| Abstract: | H2101 at Longkou Beizao colliery is the first working face mine in the sea in China.Because the sur- rounding rock is tertiary soft rock,the roadways supporting is very difficult.According to rock and soft rock creep mechanism and the principle of rheology control,this paper has established optimum calculating method of soft rock supporting and two parameters have been obtained,that is,the minimum supporting force and surrounding rock maxi- mum permission strain.It provides a theoretical basis for safe mining in the sea. |
| Keywords: | soft rock supporting creep optimum supporting force maximum permission strain surrounding rock |
