### Designing Blast Patterns Using Empirical Formulas

presented empirical formulas may be used as a good first approximation. The includ~d steps in planning a blast design and generalized blast patterns should be of help to the quarry operator. Design changes are recommended for those q~arries where problems are occurring. INTRODUCTION The Bureau of Mines has been conducting field studies of

Mar 01, 2017 · The other way is, IS 875-1 has given loading of 100mm partition wall as 1.91 KN/m² (KN/m per m height). We add the plaster in it. So, the loading shall be 1.91 + 0.02 x 20.40 = 2.32 KN/m per m height. Now, if your wall has 230mm thickness then your load will be 2.3 x 2.32 = 5.33 KN/m per m height.
