NAMIE OF APPLICANT Fleity Pty. Limited ACTUAL INVEN~DJs Philip Lamond Smith z~ujiS~ FOR SERVICE ALTERED Po~o4ko,:,k-20(4 ADDRESS !I'OR SEPVICESq 12 Ric 68 Mu- MEVNTION TITLE Contrnl Device This invention relates to a method for partitioning mine passages using a fire resistant, anti static, flexible sheet material to construct a ventilation control device.
In developing areas for extracting coal in coal mines it is necessary to drive a minimum of two spaced apart passages (headings connected by cross passages cut throughs). One heading is utilised to provide a forward ventilation path intake to the active mining face while the other carries the air from the active face to the main return airway and is itself referred to as a return heading. To do this the cross passages are closed by a ventilation control device.
There is a need for improved safety standards in mining, particularly in ventilation which is the most important function in preventing the build up of flammable mixtures of gases and coal dust as well as providing a cool healthy environment for mine workers. Good ventilation is the mine owners number one priority and a high standard practice results in safe working, S higher productivity, reduced health risks and lower production costs.
0 The development of flexible ventilation stoppings reduces costs and enhances ventilation standards by retaining their integrity under conditions of roof and floor movement. This invention provides a further method of application of a fire resistant, anti static, flexible sheet material to building ventilation control devices that remain competent, do not leak and are Sinexpensive to install.
Static rigid stoppings are subjected to strata movement including floor heave causing cracking of control devices and requiring additional costs to repair and maintain. Leakage due to cracking of rigid stoppings is the major cause of loss of ventilation air at the mining face and lowering of the overall ventilation efficiency.
A suitable flexible sheeting having a tensile strength of 160 Newton per to 8,000 Newton per 50mm and including one capable of withstanding 900 degrees Centigrade for one hour is used where required.
Continuous development of new methods of installing flexible ventilation stoppings is necessary to meet the different conditions in underground mines and take advantage of new products that are adaptable to the
Claims (9)
