TS Between Benches

Step Between Benches allows user to plan multiple bench mining in a single phase.

This setup task consists of seven main columns, each of which is described below in more details.

Between Benches step overview

Name

List of all the scheduling elements arranged in the tree level hierarchy Mine/Pit/Stage/Bench/Flitch or Dumps/Dump/Lift or Backfills/Pit/Bench. Click on a parent level to expand children levels.

Expand Distance

The Expand Distance works by taking the polygonal boundary of a blast, expanding it by the nominated distance, and checking for any unmined blocks on the bench above that are within that area.

• A zero expand distance allows vertical walls.

• A positive expand distance forces a minimum running track between crests and toes.

• A negative expand distance allows under-cutting the bench above.

Open

Blasts are dependent on blasts within the Expand Distance on the bench above

Populate multiple values in the Expand Distance column in meters or press black cross button to clear related.

Adjacent Phase Expand Distance

If you specify a number here, it will be used as the expand distance between phases. If you hit the X, it will instead use the value in expand column. See the logic below.

Max Active Benches

In the Max Active Benches column users may limit a bench from being mined until the Nth bench above is completely mined out.

Time Delay

In the Time Delay column specify the waiting period between satisfying the Expand Distance and beginning mining the block.

Max Agents on Bench

In the Max Agents on Bench column limit how many Agents can be active on a given bench.

Max Agents on Block

In the Max Agents on Block limit individual blasts from having more than the specified number of Agents on them at a time.
