ADVANTEC Tunnel & Mining Mining and tunnelling

Our mission at ADVANTEC Tunnel and Mining Solution is to forge ahead. Our roadheader machines represent the best example of this. Under the TDR series name (tunnel-digging roadheaders), we offer you powerhouses that represent the benchmark in the mining and tunnelling industry. On the one hand, because we produce our roadheaders in various sizes

tunnels and underground excavations History, Methods

2021-5-23  Tunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature’s action in dissolving a soluble rock, such as limestone. A vertical opening is usually called a shaft. Tunnels have many uses: for mining

Study of Tunnel Damage Caused by Underground Mining

Bayueshan tunnel (BYS) is an important construction crossing over coal mine goaf. The underground mining subsidence has led the tunnel cracked seriously in three years after it was built. In order to evaluate the coal mine influence and future stability of the tunnels, probability integral method (PIM) was used to calculate the tunnel deformation. PIM is an experience function method based on

Challenges and opportunities of using tunnel boring

2016-8-1  Non-conventional mining such as shale gas, natural gas and oil involves significantly different mining techniques and normally needs no TBMs for tunnel excavation. A metallic ore is a geochemical anomaly which enriches one or more particular elements/minerals to a concentration that can be economically mined.
