Abstract: Patio construction is relatively common in the process of mine production, its applicability, scientific and stability directly affects the mine safety and efficient production and management activities, traditional patio construction methods such as common method, climbing tank method has long construction cycle, high cost, poor security and a series of problems, and reverse drilling construction method is efficient and convenient, but it in the short distance on the application of the patio construction equipment transfer workload and high cost, study a low cost, safe and controllable, high efficiency of patio construction technology is particularly important. In this paper, medium and deep hole blasting technology is used for short patio construction. Through theoretical calculation and field test, the key technical parameters of medium and deep hole blasting are deeply studied and discussed. First, according to the geological conditions of short distance patio and construction requirements, reasonable layout of the gun hole, determine the blasting parameters, and then according to the previous theoretical results of field blasting experiment, observe blasting effect, collect data and optimize related parameters, finally form stable and controllable short distance courtyard a deep hole blasting a drilling technology, improve the short distance patio construction safety, construction efficiency, and effectively reduce the engineering cost, for similar mine patio construction provides valuable practical experience and theoretical guidance.
