PVS – Permanent Ventilation Seal™
PVS Permanent Ventilation Seal is a patented product developed specifically for underground mining ventilation applications in both conventional and trackless mining operations.
Unique to Biziwe (PTY) Ltd. PVS is manufactured locally at our manufacturing facility in Rustenburg, Northwest Province, South Africa and represents the main focus of our business.
PVS is designed to be installed as a permanent fixture in underground areas with a height ranging from 1.0 meter to 3.0 meters and length varying from 1.0 meter to an excess of 15 meters, which will form a vital part of the ventilation control system. Aiding in preventing the loss of airflow to a particular section by forming a contour hugging airtight seal in between pillars, strike gullies, pillar holing, t/ways, x/cuts, box holes, aiding the directional flow of fresh air to work areas.
A secondary function of PVS is restricting access to “mined out” sections by means of the steel reinforcing used to provide structural rigidity acting as a human barrier.
In addition to the above PVS is well known for its versatility in its applications and has successfully been used to construct underground waiting places and training centres.
