Abstract. Limestone mining using open pit mining method that involves vegetation removal and soil drilling and blasting in accessing limestone material has caused ecosystem damages. Natural recovery of such a harsh site is a slow process as the site condition in the successional process do not favor the natural vegetation development.

Open pit mining - Rutgers Center for Operations Research
The open pit mine production scheduling problem can be defined as specifying the sequence in which "blocks" should be removed from the mine in order to maximise the total discounted profit from the mine subject to a variety of physical and economic constraints.
Surface Mining Methods | Pit planning and layout
Open-pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.

Abstract In general, exploitation of rock materials, such as limestone or granite exploitation, can cause serious damage to the ecological environment near a mine area. With economic development and the ever-increasing demand for ore resources, mining activities have induced very serious environmental issues in China.
LIMESTONE OPEN PIT MINING EXCAVATION SLOPE STABILITY ANALYSIS
ABSTRACT . In the open pit mine limestone, particularly which is managed by the priority, design and slope stability is often not analyzed. However the slope stability problem in an open pit mine is a very important issue because it involves risks of human’s, mining equipment, and other infrastructure safety which is located around the quarry

Coal Mine Open Pit Final Void Closure and Relinquishment
This report addresses uncertainties faced by coal mine operators when assessing and planning options and implementing rehabilitation designs and methods during the closure of opencast coal mine voids to ensure safe, stable, non-polluting, and sustainable post mining void uses.
Optimization of the fleet per shovel productivity in surface
been mined. The aspect of the mining operation, which has the most influence on profit, is the cost of materials handling. This paper focusses on developing an oriented algorithm that can be used during the calculation of shovel productivity as well as fleet production management for an open pit mine.
ABSTRACT - Taylor & Francis
Rehabilitation of post-mine land in open-pit coal mines is necessary for sustainable development of coal. Although topsoil containing much nutrition should be secured for plant growth, there was the shortage and the erosion of topsoil by heavy rain in the tropical climate, especially in South East Asian countries.
