Abstract:

Currently, along with the economic development speed and the huge demand for activities and living in Vietnam, the demand for energy is becoming an urgent problem that needs to be solved. Among all types of energy, coal is one of the types of energy that occupies a large proportion of the energy industry in Vietnam. Therefore, it is necessary to develop mining technologies that can boost the efficiency and quality of coal. In the total annual coal production of Vinacomin, underground coal mining output accounts for a large proportion (60÷80%). At present, the design and construction units have applied many different construction methods to prevent and stabilize the mining tunnels in the Quang Ninh area. However, in some mining tunnels, are still occurred phenomenon of instability, excessive deformation and affecting the exploitation of these mining tunnels. The paper aims to synthesise, analyse and give a process of choosing suitable reinforcement methods that are suitable for mining tunnels in the Quang Ninh area. The paper also applies theoretical bases to selects an appropriate reinforcement method for a specific mining tunnel under construction in Khe Cham I mining area, Ha Long Coal Company, Vinamcomin.
