Globigerina Limestone is quarried for use as a building stone while Coralline Limestone is quarried for use as spalls. Many of the old quarries have been worked out and abandoned, often without any form of reclamation. New quarries are being established but in some cases in ecologically sensitive areas, such as in valleys and close to cliffs.

Reclamation of Degraded Landscapes due to Opencast Mining

Jul 01, 2013There are different terms that have been used for reclamation such as rehabilitation, restoration and recultivation. Whereas these terms are mostly used interchangeably, there are obviously some fine differences in meaning. Restoration is used as "the act of restoring to a former state or position or to an unimpaired or perfect condition".

Cultivation is also determined by slope gradient and exposure. The use of sloping land also depends on the technique applied in cultivation. Hoe horticulture can be used for steep slopes, whereas mechanical cultivation can be used only for gentle slopes. Primary (forest or grassland) vegetation provides protection for the surface against

At an working quarry, Vetiver was used to stabilise steep slopes of overburden and waterways. When planted across a long (500m) and steep (20%) waterway, Vetiver hedges stopped the erosion on the waterway floor and trapped both coarse and fine sediment in runoff water from this working quarry.

Heavy tropical rains and typhoons can cause very high flows in the rivers leading into the Ambuklao and Binga reservoirs. PMF peak flow is 11,600 cumecs. Due to the steep slopes surrounding the reservoir and along the access roads to the Binga Dam, landslides can create a hazard in the reservoir or for emergency access to the dam.

Steep Slopes. Steep slopes are defined as having an incline of 25% or greater. Protecting the natural terrain and vegetative features present on steep slopes prevents flooding, stream siltation, and the alteration of natural drainage patterns.
