REPORT ON THE DESIGN OPTIONS OF LANDWALL MINING METHOD PART 1: RISKS IN LANDWALL MINNG Accidental collapse of the walls in underground mining The mining options presented have got a myriad of challenges such as risk factors that must be analyzed during establishment of standard operating procedures. Admittedly, risks associated with each mining option have unique characteristics such as accidental collapse of the roof in areas where reinforcements are not done properly. The cross deep shaft method is often associated with this kind of risk as the shafts are sunk relatively deeper. Due to the overbearing weight of the earth movers and the vibration of the machines, areas prone to earth quakes may betriggered off. The geologists must therefore competently analyze the data from the area using modern sophisticated tools and software. The identified hotspots must therefore be avoided at all costs. Workplace safety concerns Improper and insufficient training of all workers can also be a potential source of problems. The inexperienced crane operators and drivers may cause damage to people and properties as they tryto navigate the terrain during mining. The entire system of mining must therefore take into consideration the complex routing of the machinery and equipment to minimize on backtracking and unnecessary collisions (Singh & Unver, no year). Some mines have weaker rocks which could cave in during operation. It is therefore often required that once an area is depleted, the remnants must be cleared off. The belt transect methodwill come in handy in this case. The wall destabilizers are therefore useful for this purpose. Notably, the proposed designs aim at maximizing the extraction potential while at the same being cognizant of the fact that safety and costs are equally critical aspects in the operation. The above mining design options have got both merits and limitations. The belt transect method is the fastest and perhaps the cheapest to establish and run. The area identified is worked on in a rectangular manner before collapsing the weaker walls to give way to new region as movement is both traverse and longitudinal.

The best strategy is selected after a thorough evaluation of the available options. Different models have been used. In our case, a simple yet effective model is used to ascertain whether the minimum criteria are met.
