[0023] The present invention includes a special explosive and a preparation method of the special explosive;
[0024] Said special explosive: raw materials and their mass percentages include: 60-95% of 2# rock ammonium nitrate explosive; 2.5-20% of common salt; 2.5-20% of expanded perlite; said common salt is sodium salt;
[0025] The preparation method of the special explosive includes: drying and grinding process of raw materials, weighing and mixing process, and the specific method process is as follows:
[0026] a, drying and grinding process: the granular table salt and expanded perlite are naturally dried to make their moisture content less than 0.3%, and they are respectively ground to make their particle fineness the same as that of 2# rock ammonium nitrate explosive; Drying is air-drying or oven-drying;
[0027] b. Weighing ingredients and mixing process: Weigh ingredients according to the above raw material formula, then put the above three raw materials into a mixe...
Embodiment 1
[0029] Embodiment 1: raw material composition and mass percentage thereof are as follows: 2# rock ammonium nitrate explosive 70%; Salt 15%; Expanded perlite 15%;
[0030] The preparation method includes: drying, grinding process, weighing ingredients and mixing process, and the specific method process is as follows:
[0031] 1) The purchased table salt and expanded perlite often have relatively high moisture content, so they need to be air-dried in a natural environment or put into an oven for drying, so that the moisture content does not exceed 0.3%.
[0032] 2) Grinding process: Since the 2# rock ammonium nitrate explosive is easy to agglomerate, it needs to be put into a container to crush the agglomerates to make it into a powder, and ensure that more than 85% of the explosive can pass through the 24 hole.cm -1 Sieve cloth; the air-dried or dried table salt (sodium salt) and expanded perlite are subjected to grinding treatment after removing impurities, and the fineness o...
Embodiment 2
[0034] Embodiment 2: raw material composition and mass percent thereof are as follows: 2# rock ammonium nitrate explosive 70%; Salt 12.5%; Expanded perlite 12.5%;
[0035] The preparation method includes: drying, grinding process, weighing ingredients and mixing process, and the specific method process is as follows:
[0036] 1) The purchased table salt and expanded perlite often have relatively high moisture content, so they need to be air-dried in a natural environment or put into an oven for drying, so that the moisture content does not exceed 0.3%.
[0037] 2) Grinding process: Since the 2# rock ammonium nitrate explosive is easy to agglomerate, it needs to be put into a container to crush the agglomerates to make it into a powder, and ensure that more than 85% of the explosive can pass through the 24 hole.cm -1 Sieve cloth; the air-dried or dried table salt (sodium salt) and expanded perlite are subjected to grinding treatment after removing impurities, and the fineness ...
