This text is about how to mine thickness as 0.5 m about thin coal seam circle at present, Puts forward one unique exploitation system , breaks through worker enter working range to finish fall, load, production process of transporting of coal in the past, Realizes and no-operator workface . And on the basis of a large number of experiments, according to the questions which appearing in the course of exploiting which hole and make location and pipeline effect issue that deep hole blow up develop accurate a directional one light-duty to bore a shelf of equipment, Put forward and adopt the way of improving the speed of producing and detonate a bit more and can overcome pipeline effect to influence that deep hole blow up at the same timeThis text is innovational studies, while putting forward this new exploitation system, Extracting, loading and hauling equipment system makes a large amount of research even to working range, Adopt hydraulic pressure pass system come and realize working range conveyer move while being whole, Deep hole blow up and fall coal form an intact craft system with working range, Have practical effectiveness.
Keywords/Search Tags:no-operator working face, pipeline effect, laser orientation, deep-holed explosion
