| 中文摘要: |
| 淮北袁店二矿岩巷地质条件多变，以袁店二矿101采区运输石门及运输上山为例，根据实验室测定的围岩典型岩性，采用数值模拟结合现场实测，确定软岩、硬岩条件下合理的锚杆索支护参数。研究结果对于保证围岩变形的稳定、确保安全生产，提高掘进速度、降低工程成本有一定指导意义。 |

| The geological conditions are complicated in Yuandian No.2 mine in Huaibei. Selcting the transporting up cross-hole and the mountain of 101 mining area in this mine as an example, according to the typical laboratory determination of surrounding rock lithology, the reasonable anchor supporting parameters were determined under the conditions of soft rock and hard rock by using numerical simulation based on field test. The results of the study had certain guiding significance to ensure the deformation of surrounding rock stability, ensure the safety in production, increase the driving speed, and also reduce the cost of the project. |
