South Station In Yichang Chamber Blasting Technology Research

Cave blasting up a method is the method which packs a great deal of explosive into the cave and the tunnel to carry on blasting up. In order to blasting up once of pack amount of medicine and explode to fall a square to measure more and greatly, so often be called "blow up greatly". The our country is to carry on cave to blow up most of nation of a, ten thousand ton class the explosive blow up three times, more than ten time of the kiloton class, 100 tons reach a hundred times above, backlog abundant of experience.The cave blows up a method not to need a large machine, the our country is the nation of the labor force intensive type, can organize a great deal of physical labor to carry on leading cave and medicine room to open to dig in the meantime, carrying out cave to blow up homework time short, the cost is low, so at many important engineering foundation, places the neat engineering is under construction, the cave blows up to develop an important function. Along with our country large drill a hole and open development and renewal of digging the machine tool equipments and blow up environment of complicate and blow up increasingly to surroundings the influence control of the region degree request of exaltation, a great deal of stone square open to dig engineering have already adopted deep bore to blow up a method extensively currently, but the cave blow up of the application is subjected to restriction. But, some ground squares in our country are under construction, especially some important foundations in western development, research improvement of the cave blow up comprehensive technique, such as the form medicine wrap cave to add to prepare to split to model once of comprehensive blow up a technique, still will have considerable of applied foreground.The basic theories that this text inquiry into from the theories, design construction important point, and emphasized to discuss cave to blow up of key problem, then lower a big piece rate, exaltation to toss a rate and raise an economic performance, put forward a homologous solution. With proper ten thousand railroads proper Nanchang station cave blasting example, concretely carried out cave to blow up of design and construction process, to the alike engineering draw lessons from meaning very greatly. Is the summary of construction in the meantime, also benefit in summary experience, detection shortage, have for the later work aggressive function.
