At approximately 4:00 pm January 29, our longwall Tailgate had closed off enough that we needed to go on our Longwall Tailgate Blockage Plan. Field Office Manager was contacted. A field inspector came to the mine and issued a K-Order. We properly trained our LW miners and set up to mine under the TG Blockage and K-Order. The TG Blockage was due to an unforseen displacement.
