How will it affect the rock layers mining?

How will it affect the rock layers mining?

Answer: The change in overburden structure resulting from mining causes horizontal tension on the surface, while vertical shear occurs due to the movement of overburden in the vertical direction.

What occurs when layers of rocks slip along a fault?

Earthquakes occur on faults. A fault is a thin zone of crushed rock separating blocks of the earth’s crust. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.

How many will affect the rock layers?

What are 5 ways that the order of rock layers can be disturbed? Folding, tilting, faults, intrusions, and unconformities all disturb rock layers.

What are the primary components involved in processing of minerals?

The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering. …

What type of fault shifted the rock layers?

strike-slip fault, also called transcurrent fault, wrench fault, or lateral fault, in geology, a fracture in the rocks of Earth’s crust in which the rock masses slip past one another parallel to the strike, the intersection of a rock surface with the surface or another horizontal plane.

How do rock layers change order?

How Can Rock Layers Change?

  1. How can rock layers change? Photo by arbyreed.
  2. Rock layers can be eroded.
  3. Rock layers can be tilted.
  4. Rock layers can be folded.
  5. Rock layers can shift due to faults.
  6. Igneous intrusions can move through rock layers.
  7. Extrusions occur when magma reaches the Earth’s surface.

What are the processes associated in mineral processing?

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

How are sediments deposited in the rock layers?

This law of science tells us that dirt, mud, sand and other sediments are almost always deposited in horizontal layers. As these sediments stack up vertically, they often harden, forming rock layers.

How are the layers of a rock ordered?

Rock layers are usually ordered with the oldest layers on the bottom, and the most recent layers on top. The Law of Faunal Succession explains that fossils found in rock layers are also ordered in this way.

What happens to a rock during brittle deformation?

Rocks that undergo brittle deformation tend to fracture into joints and faults. 1. Figure 10.20: A joint is a crack in a rock along which no appreciable movement has occurred. Strata on one side of the joint align with strata on the other side.

What causes the stretching and thinning of rocks?

Compressive forces are common along convergent plate boundaries resulting in mountain ranges. (b) Fig. 10.6b: Tensional forces cause stretching and thinning of the rocks, usually accompanied by tensional faults. Tensional forces common along extensional plate boundaries such as mid-ocean ridges.
