Abstract:

The paper uses numericai simulation method and analysis theory to assess stress around the underground construction, on coal pillars to study the stability of the underground construction. Reseacrch results have shown that the protective coal pillars has a great influlence on the stability of the underground construction and the loss of resources. Therefore, the authors have studied the method of none leaving the coal pillar protection and the application of directional rock cutting techniques. The research results have proved the superiority of this method n compared to prsvojs methods in ensuring underground oonsbucfion stability and reducing coal loss.
