Abstract:

The strategy for Vietnam's coal industry in the period to 2030 is to continuously increase the mining output. In particular, the structure of shifting to coal mining by underground method will be essential. However, the increase in underground mining output is affected by many factors. Currently and in the future, almost all underground coal mines in Vietnam must expand their mining areas, apply advanced technology, to meet the increase in mining output. However, a long - standing problem that the underground coal mines in Quang Ninh have not improved much is speeding up the digging. This is one of the problems causing congestion in production when it is necessary to increase production. The article has studied the design and application of a mobile hydraulic anti - rigid complex for tunnel excavation and mining at Mong Duong Coal Company - Vinacom. This is a type of advanced technology in tunnel excavation and mining, which has been researched and applied in the world in recent years, in order to speed up the speed and ensure very effective safety. The application of a mobile anti - rigs in tunnel excavation will solve the current urgent requirement of speeding up the excavation progress by 30÷50% and ensuring labor safety. The article has researched and designed the excavation of a underground tunel through the seam at the in level - 400 m at Mong Duong Coal Joint Stock Company - Vinacomin. The underground tunnel the seam at the in level - 400 m is excavated underground tunnel with relatively typical conditions of underground coal mines in Quang Ninh region. The experimental design and application will be universal and increase the reliability of this type of advanced technology in the orientation of the underground coal mining industry in our country.
