Determining Stripping Ratio Basic Mining Techniques Pdf Mining Determining stripping ratio basic mining techniques free download as pdf file (.pdf), text file (.txt) or read online for free. mining open pit. Establishing pit limits requires geometric modeling and economic factor analysis. the cutoff grade adjusts cash flow and determines ore versus waste classification. the overall stripping ratio must always be less than the instantaneous stripping ratio at the pit limit.

Determining Stripping Ratio Basic Mining Techniques Pdf Mining Stripping ratio simply refers to the amount of waste handled in order to recover certain amount of ore. it is mathematically expressed as the ratio of waste to ore. Tio would then be calculated from that value by using several scenarios of striping ratio, which are: sr 4,5; sr 5,5; sr 7,5; sr 9,5; sr 1,5; and sr 13,5. based on the cash margin approach, the value of the optimal striping ratio is 8,23 bcm ton with a cash. Pre mining geological structures, particularly fault planes, represent zones of potential weakness in the rock mass, and are therefore zones of potential slope failure, and should be taken into account when designing the mine. The parameter known as the stripping ratio represents the amount of uneco nomic material that must be removed to uncover one unit of ore, i.e., the ratio of the number of tons of waste material removed to the number of tons of ore removed.

Stripping Ratio Pdf Pdf Coal Mining Economic Geology Pre mining geological structures, particularly fault planes, represent zones of potential weakness in the rock mass, and are therefore zones of potential slope failure, and should be taken into account when designing the mine. The parameter known as the stripping ratio represents the amount of uneco nomic material that must be removed to uncover one unit of ore, i.e., the ratio of the number of tons of waste material removed to the number of tons of ore removed. Ing out 1 ton of ore how much waste rock or overburden rock is required to be excavated and taken out for getting that 1 ton of ore. so, this ratio is called stripping ratio. now, if you look into this figure, you can see this is the ore, which we need to excavate and the total ore tonnage is b, but to take. Pdf | the article contains the research results for a rational mining mode, definitions, and averaging of the operating stripping ratio. Stripping ratio refers to the ratio of the volume of overburden (or waste material) required to be removed to the volume of ore recovered. for example, a 3:1 stripping ratio means that mining one cubic meter of ore will require mining three cubic meters of waste rock. Maksud dari penelitan ini adalah menentukan tahapan penambangan yang memberikan nilai ekonomis dalam penambangan batubara. tahapan penambangan ditentukan menggunakan analisis break even stripping ratio (besr). model yang digunakan yaitu besr bervariabel yaitu menggunakan harg.
