Calculating Stockpile Capacity
Know More
Calculating Stockpile Capacity Once the minimum storage capacities which will assure maximum mill output are known the appropriate stockpile configuration must be determined Stockpiles fall into two general categories conical and elongated Conical Stockpiles The conical stockpile is the simplest and easiest to analyze The total stockpile capacity is given by 314 Tan A R³ D/3000...
Gravel diaphragms
Know More
Gravel diaphragms are simply gravel filled trenches which act as inlet structures by redistributing concentrated flow to sheet flow reducing the erosive power of the water and promoting infiltrationThey also act as a pretreatment by settling out sediment Soil sand and minerals washed from land into water usually after rain They pile up in reservoirs rivers and harbors destroying fish...
