Abstract
Inventia se refera la un exploziv de înalta siguranta destinat lucrarilor de împuscare cu încarcaturi alungite în gauri sub protectie de apa, Constituit pe structura explozivului DS (detonatie selectiva) are în compozitie saruri schimbatoare de ioni si o substanta cu proprietati hidrofobizante si gelifiante pentru marirea rezistentei la apa, fara a se modifica detonabilitatea si siguranta sistemului. Prin aplicarea inventiei devine posibila utilizarea unor tehnologii noi cu mare eficienta la exploatarea stratelor subtiri de carbune, în prezent neexploatate cu tehnologiile existente, în conditii de siguranta în minele grizutoase si face posibila efectuarea lucrarilor de împuscare în conditii de siguranta în minele de petrol.The invention relates to a high-explosive explosive designed for long-range fireworks under water protection. Based on the DS explosive structure (selective detonation) it has ionic salt salts and a hydrophobic and gelling agent to increase resistance to water without changing the detonability and safety of the system. By applying the invention it becomes possible to use new technologies with great efficiency in the exploitation of thin coal layers, currently untapped with the existing technologies in safe conditions in the grizzled mines and makes it possible to carry out the safe shooting works in the oil mines.
