Inhaltsangabe

Excerpt from Ore Mining Methods: Comprising Descriptions of Methods of Support in Extraction or Ore, Detailed Descriptions of Methods of Stoping and Mining in Narrow and Wide Veins and Bedded and Massive Deposits Including Stull and Square-Set Mining, Filling and Caving Methods, Open-Cut

Methods Of mining and support of workings are so closely related that the discussion Of one necessitates a more or less detailed treatment Of the other. It therefore seems eminently proper and even necessary to preface a work of this character with a brief discussion regarding the elements of support. A description Of the elemental units of support, such as pillars, props, cribs, stulls and square sets will not therefore be out Of place in this connection. Further, the use Of filling is considered, as it is rapidly becoming an important factor in the support Of under ground excavations; caving as a factor in support is also discussed.
