Backfilling Trenches and Other Excavations

With the jetting technique, you pump the water under pressure and use the force of the jetted water to move the bedding or backfill material around. As with any backfilling, the material should be placed slowly and in lifts. After the water is applied, it is allowed to drain from the soil to improve compaction.

Paste Backfill Fundamentals

Slimes draining from hydraulic sandfill operations often pose housekeeping problems, cause wear on mine dewatering pumps, and pose safety problems if dumped in ore passes. These problems are solved with paste backfill. The mining cycle time is less with paste backfill system because strength is achieved earlier than with hydraulic sandfill.

Surface mining

Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

What is Earthing Electrical Notes amp; Articles

Nov 27, 20110183;32;Introduction The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipments are grounded then if the insulation inside the equipments fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is effectively shorted

Types of Mine Backfill MiningInfo

Paste Backfill. Paste backfill is a high density backfill (gt;70% solids depending on SG). In order to pump material at this density, a component of fines is required. As a general rule, the fines content (lt;20 micron) should be a minimum of 15% by weight; The slump of paste backfills is
