Mine closure or the process of shutting down a mining operation on a temporary or permanent basis requires long-term planning to avoid infliction of any harm to the environment or society. It is a complex and multi-disciplinary activity which requires legal, engineering, social and scientific professions.

Mine closure planning is very important. Unintentional consequences may arise if mine closure is not well-planned and not adequately managed. It may reduce employment levels, cause health related problems, and environmental problems which can have a negative impact on local economies.

Once a mining operation is over, decommissioning process follows. Activities during the process include but are not limited to draining, cleaning, and selling parts of pipelines, disposing wastes, recovering warehouse materials, removing of facilities and equipments, and demolishing or repurposing buildings or structures.

After the decommissioning process, remediation or reclamation takes place. The process is aimed towards a more productive and useful ecosystem. It involves the restoration or conversion of a mine area into a land which is more suitable for cultivation.

Abandoned mines prior to the introduction of mine closure posed great possibility of contamination in the environment. The environmental concern have lead today’s governments to create standards and regulation controls on mine closure.

Capping is an effective and proven technology.  It serves as physical barrier that prevents direct exposure to solid mining wastes and contaminants. In most cases, a large, thick and concrete plug is placed over a mine shaft to avoid accidents and eliminate soil erosion, dust emission, and infiltration of water. Removal or reduction of such will mitigate the spread of contaminants.   Capping requires maintenance to ensure its effectiveness.

Today, engineers have looked at a new approach to establish a more improved and physically stable environmental solution through an exposed geomembrane system. LiteEarth is an aesthetic capping system that provides a rapid installation and more stable mine cover while reducing emissions, erosion, and sedimentation through the use of synthetic turf or artificial grass. The system is made up of EPDM geomembrane and synthetic grass, and has an extra protective layer which makes it more effective and durable. It is also highly recommended for being a cost efficient system. Unlike traditional capping system, LiteEarth provides a long term closure through high quality artificial grass or synthetic turfs which do not pose any danger to human health and environment.
