Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock mass breaking equipment, in particular to a rock mass drilling, slotting, hole sealing, fracturing and breaking integrated equipment and operation method, and is particularly suitable for medium-intensity or above roadway tunneling and ore body resource mining. BACKGROUND

[0002] With the increasing demand for coal energy and metal mineral resources in China, the problems of unbalanced mining and low efficiency of strategic metal mineral resource mining caused by difficult rock mass breaking have become increasingly prominent. With the mature application of coal mining mechanization, the mining efficiency has been greatly improved, and the phenomenon of unbalanced mining and mining has become more prominent. The mechanical breaking equipment for medium-intensity or above rock mass has become a "bottleneck" restricting the coordinated development of coal mining and roadway tunneling, and the deep strategic hard ore body resource mining almost entirely relies on drilling and blasting. Especially for medium-intensity or above rock mass (with a Protodyakonov hardness coefficient of 8 or above), the impact and wear of the mechanical breaking equipment and its installed cutting tools are increased during construction, and the working environment of the mechanical breaking equipment is more severe. The mechanical breaking of rock mass has poor effect, low efficiency and high operation cost.

[0003] In the existing technology, drilling and blasting and mechanical pick breaking are often used for breaking medium-intensity or above rock mass. Although the drilling and blasting method has strong applicability to the stratum, it has low efficiency, large dust and toxic gas emissions, complex procedures, and is prone to cause major accidents such as gas explosion, which is not conducive to safe, efficient and green mining of underground ore resources. The hard rock breaking by the pick is difficult and has a large load, and the pick is easily damaged and needs to be frequently replaced. The rock mass breaking efficiency is low and the cost is high. The narrow space test proves that the pick cutting and breaking rock method is difficult to realize the mechanized and economic breaking operation of medium-intensity or above rock mass. It is urgent to break through the mechanized and efficient breaking technology of medium-intensity or above ore body to ensure the safety of China's strategic mineral resources. SUMMARY
