| 中文摘要: |
| 为提高袁店二矿101采区运输上山及石门岩巷快速掘进速度，本论文通过现场实测围岩表面变形随时间变化以及围岩松动破碎范围，结合数值模拟对目前支护合理性以及存在问题进行了分析；针对该巷道具体工程实际，确定了合理锚杆支护参数，实现岩巷高效优质快速掘进。 |
| 英文摘要: |
| For improving the rate of rapid excavation in rock roadway of the transporting up the mountain and cross-hole of 101 mining area in the second coal mine of Yuandian ,the paper analyzed the rationality of supporting and existing problems at present by the measured, according to the deformation of surrounding rock with time,and the scope of loose and broken of surrounding rock, meanwhile in combination with the numerical simulation.Aiming at the specific engineering practice of this rock roadway, the bolting parameteic rational was determined,and the quick tunneling of the rock roadways with high quality was realized. |
