Estudio técnico-ambiental de las estructuras principales de fortificación usadas en la minería de carbón de Norte de Santander

Abstract: <p align="justify">La caracterización de las estructuras de fortificación en la minería de carbón en Norte de Santander (Colombia) y el aporte de este sector a la deforestación han sido poco estudiados. La pérdida de bosques entre 1990 y 2010 en el departamento fue del 26%, y la contribución a ella de la minería de carbón, es de 0,36%. Se determinaron 17 variables geométricas de la estructura, de las cuales sólo dos influyen en el comportamiento mecánico de la estructura. Mediante una simulación estructu… Show more

“…The structure under study is called the German Door and is a set of three commonly cylindrical woods, which are assembled in the shape of a trapezoid and are used as support for the mining operation [2]. The parts that make up the German door are a wood called a pencil that acts as a support beam, two woods called levers, which act as columns or parapets and a wooden lining or ceiling of the German door, in addition to some final adjustment blocks against the wall of the mine [3]. Figure 1 shows the general components of the door.…”
