[0003] However, due to the fact that there is only one free surface in the blasting operation of deep hole excavation in coal mine roadways, the rock clamping effect is great, and the blasting operation conditions are poor. Low efficiency and other issues. According to relevant data, shallow-hole multi-cycle drilling and blasting excavation methods are mostly used in coal mine rock roadways in my country. This excavation method blasts a small amount of stone at one time, so there are more blasting times per month. At the same time, the blasting noise and The vibration is also relatively large and has an impact on the surrounding environment and residents. In the long run, it is not conducive to reducing the mining cost of investors and improving economic benefits.

Description
technical field [0001] The invention relates to an excavation system, in particular to a deep hole efficient excavation method and system. Background technique [0002] At present, there are mainly two operation methods for rock roadway excavation in coal mines in my country: one is drilling and blasting construction, and the other is mechanical excavation construction. The degree of mechanized excavation of rock roadways in my country is very low, and the drilling and blasting method is currently the main rock roadway excavation method in my country because of its good applicability. [0003] However, due to the fact that there is only one free surface in the blasting operation of deep hole excavation in coal mine roadways, the rock clamping effect is great, and the blasting operation conditions are poor. Low efficiency and other issues. According to relevant data, shallow-hole multi-cycle drilling and blasting excavation methods are mostly used in coal mine rock roadways i...
