The high sulfur coal mine using ammonium nitrate explosives
1. in high sulfur coal mine using ammonium nitrate explosive blasting, iron ion concentration and sulfur content should be measured in advance of sulfide ore powder.
2. when the sulphur content of more than 30%, ferric sulfate and sulfite powder containing iron and iron ion concentration of more than 0.3% operations in the face of wet water, using ammonium nitrate explosive blasting, blasting hole shall be cleaned powder; explosive and hole wall should not be in direct contact with explosives; should the packing should not use sulfur slag; filling the hole; strictly control the charging time and hole number.
