Description
Technical field
The invention belongs to down-hole developing technology, specifically a kind of stone drifting technology that is adapted to down-hole rock lane comprehensive mechanization developing operation.
Background technology
At present, all kinds of rock roadway in coal mine drivings of China generally adopt the big gun pick, and support pattern is anchor pole, anchor cable, joist, anchor net combination supporting.The big gun pick is the perforating of gas leg type air drill; The manual charging, blow out; Blow out the spoil that falls, artificial fragmentation earlier adopts rock rake to transport work plane again; After the work plane spoil cleans out, use the monomer air drill to carry out the anchor shaft anchor cable supporting.Mainly there is following problem:
1, the mechanization equipment level is very low: the down-hole rock gangway mechanized of China has developed decades, but present most of operation is still leaned on artificial the completion, and the mechanization equipment level is very low;
2, tunnelling footage is low: because most of operation is leaned on artificial the completion, so rock gangway list drilling depth is very low, big section drill footage per month generally has only about 50m;
3, personnel selection is many, and work efficiency is low;
4, labor strength is big, and operating environment is poor;
5, safety factor is low.
Summary of the invention
The object of the invention is exactly low to mechanization equipment level in the existing rock gangway construction, and the problem that stone drifting technology is relatively backward provides a kind of stone drifting technology that adopts advanced technical equipment; Realize rock gangway construction comprehensive mechanical equalization, reach and improve stone drifting drilling depth level, reduce labor strength; Subtract the people and put forward effect; Improve site work environment, reduce the generation of occupational disease, realize the purpose of safety in production.
To achieve these goals, technical scheme of the present invention is:
Four arm hydraulic drill rigs and broken stone drifting technology of loading and transporting the spray integral machine; It is characterized in that adopting four arm hydraulic drill rigs to carry out blast hole drilling, eyeshield and anchor shaft anchor cable supporting, and adopt the broken shipment of rock gangway that integrates brokenly rock, muck, Yun Yan, whitewashes to spray integral machine and match and carry out the rock gangway operation; Concrete construction sequence comprises as follows:
