Safety evaluation of mine lane tunneling project based on grey relation analysis

摘要

In order to understand the security situation in the process of coal lane tunneling project effectively, this paper determines the safety evaluation indicators according to the actual situation in the coal lane tunneling, and then combining the indicators using grey relation analysis to evaluate the security situation of the sample coal lane tunneling projects. The evaluation method is simple, and compares the security situation of the various coal lane tunneling projects, so it can provide a reliable basis for the safety evaluation of the coal lane tunneling projects.
