  • Automated support of a gate entry for underground full extraction mining
    Patent number: 10890068
    Abstract: An apparatus, system, and method for automated support of a gate entry for underground full extraction mining that includes gathering entry data for a condition of a gate entry by way of a gate entry support. The method also includes determining, by way of the gate entry support, the condition of the gate entry, advancing the gate entry support in response to determining that the condition satisfies an entry condition threshold. The method may also signal a halt condition for a production cycle, if the condition fails to satisfy the entry condition threshold.
