This work dissertation proposes the applicability of methods that are similar to the technique of burn cut area to open underground tunnels, however, is facing the opening to "shallow well" (shallow wells) for placement of concrete poles for support of electrical networks in the state of Bahia. The field work was conducted in the region where is action the Energia Brasil Projetos e Construções Elétricas Ltda, a company in which donated the location for the realization of the project. Have been suggested five distinct configurations of drilling and applied in the field, without neglecting the parameters tha rules the rock blasting, such as burden, spacing, hole length, stemming, drill angle and power factor, aiming to better use in load distribution in short wise, causing the material to be broken efficiently. All work in the field were performed using five different combinations of configurations of holes, classifving them into: methods 1, 2, 3, 4, 5. All five methods were categorized by photographic record. The feasibility of practical work had as its factor primary the safety. Therefore, will be studied methods to avoiding flyrocks fragments during blasting of pits with muffling during rock blasting in the short wise, reducing damage to third parties.

Se realizan los cálculos de los parámetros termodinámicos de explosivos militares conocidos y utilizados con mayor regularidad, mostrando paso a paso como se realizan y tabulando los resultados, para lograr una comparación entre ellos. La estimación teórica de los parámetros termodinámicos permite considerar qué tipo de explosivo utilizar con más efectividad. Con los resultados obtenidos al realizar el cálculo de los parámetros termodinámicos, se puede hacer una formulación real que coincida con los datos teóricos ideales.
