Gas outburst can result in great loss of life and property during tunnel construction. tunnels non-coal formation is often more harmful than that coal-bearing formation. In order to take effective countermeasures prevent the occurrence gas construction, it essential assess risk before This paper attempts establish an assessment system for evaluating survey phase tunnelling based on attribute mathematical theory. Based principle relevance operability, eight factors influence are selected as...
Forced ventilation or newly built vertical shafts are mainly used to solve problems in large underground cavern groups. However, it is impossible increase air supply due the size restriction of construction roadway, resulting deterioration. Based on Jinzhou oil storage project, we proposed both a summer scheme and winter scheme, after upper layer excavation completed connected with shaft. A three-dimensional numerical model validated field test data was performed investigate velocity CO...
The stability of ground surface along tunnels in karst terrain is influenced by complex factors, among which the features are significant ones. Under influence karst, very easy to collapse, thus causing great casualties and economic losses. To provide guidance for maintaining tunnels, an analysis system proposed assessing based on improved fuzzy comprehensive evaluation. Based case collapse review related researches, evaluation index assessment was established. ridge‐shaped membership...
This paper is to investigate the geological prediction in front of working face during tunneling. As tunneling a dynamic process and each detection method has its adaptability, an integrated system was proposed. The divided into four stages. stages are complement verification for other achieve reliable result. then applied practical Doupengshan Tunnel on high speed railway from Guiyang Guangzhou, China. From application, finalized result obtained, which suggested that can obtain

Based on the construction of high risk tunnels in Guiguang-Guangzhou high-speed railway, several new technologies were developed for high-risk tunnel construction. First, an integrated advanced geological prediction was tunneling karst area. Then, a system ventilation by involving dedusting technology proposed and used field, which received good air quality. Finally, method to minimize distance between working face invert installation optimizing adopting micro bench method. Applying project...
