Choosing of support during resupporting of mine workings As it is known, safety is one of the fundamental problems in the process of roadheading. Rockbolts Swellex™ by Atlas Copco Company is a new type of a rockbolt meeting all requirements. The rockbolt type provides % of stated bearing capacity being more Stabilising Mine Workings with PFA Grouts: Environmental Code of Practice (BR ) (Building Research) [STABILISING MINE WORKINGS WITH PFA GROUTS -] on *FREE* shipping on qualifying offers.

mine when it has become unsuitable for further use. The primary ventilation system thus consists of an intake or intakes (or downcasts) through which the fresh air passes, the mine workings, and an exhaust or exhausts (or upcasts) where the air passes after having ventilated the working places of the ://~tien// The mine plan is defined in this code of practice as the set of plans, cross sections and longitudinal sections showing the entire workings of a mining or quarrying operation. Other plans may be required as set out in Section There is also a need to keep a survey book in the survey office. This book should be in hard copy and should (3) Each responsible person at a mine must ensure that appropriate precautions are taken and written safe working procedures are followed if open pits are excavated through abandoned underground workings, or in close proximity to current underground workings.

While the mine workings are small the overlying rocks support themselves of and the full pressure does not come upon the mine Caving p i llars. 0 While abundant warning of the caving-in of the workings is thus given in advance it may happen that men are unexpectedly imprisoned Entry - The main entrance and travelling passage of the mine. Examiner - An official who patrols a mine section to examine the workings for accumulation of gas and other hazards. Face - The end wall at the working extremity of any excavation in a mine.
