特殊地质构造条件下的井下巷道断面设计

Cross-section Design of Underground Roadway under Special Geological Structure Conditions

井下巷道断面设计的合理性对巷道的掘进安全和使用有效性有直接影响,特别是随着矿井回采深度的不断增加,井下地质条件越发复杂,如何确保巷道断面设计更加适合实际意义重大。以此为着手点,针对特殊地质构造条件下的井下巷道断面设计开展探究,对巷道设计方案与实际施工方案进行比对分析,并对实际施工方案应用效果做出总结探究。结果表明,改进后的巷道掘进面布设方案不仅更加贴合实际使用需求,还实现了作业综合效益和安全性的全面提升。

The rationality of cross-section design of underground roadway has a direct impact on the safety and effectiveness of roadway excavation,especially with the continuous increase of mining depth,the underground geological conditions become more complex,so it is of great significance to ensure that the cross-section design of roadway is more suitable for practice.Taking this as a starting point,this paper explored the cross-section design of the underground roadway under the special geological structure conditions,compared and analyzed the roadway design scheme with the actual construction scheme,and summarized the application effect of the actual construction scheme.The results show that the improved roadway heading face layout scheme not only meets the actual needs,but also improves the comprehensive benefits and safety of the operation.
