摘要
水盘高速公路发耳隧道为高瓦斯隧道,地处煤与瓦斯突出矿区,设计穿越17层煤,穿越的煤层具有煤与瓦斯突出危险性,设计吨煤瓦斯含量为8.63m3,实测煤层吨煤瓦斯含量最高为12.96m3。发耳隧道严格按照井工开采模式进行施工管理,与普通隧道相比,施工费用大幅度提高,作者通过施工实践总结,探析高瓦斯隧道施工费用增加部分的测算方法。
Faer tunnel of Shuipan Expressway belongs to high-content gas tunnel, and it is located in coal and gas outburst mine area. It is designed across 17 coal seam which has coal and gas outburst danger. The ton gas content in coal is 8.63m3 in design, and in the real measurement is up to 12.96 m3. Faer tunnel strictly follows the underground mining models to conduct construction management. Compared with the common tunnel, its construction cost has a significant increase. Through construction practice, the author analyses the measurement method for costs increase part in high-content gas tunnel construction.
