Beneficial effect of the present invention:
1, disposable perforate in hard rock is realized, simple to operate, the degree of accuracy is high, reduce costs, improve perforate efficiency, solve the problem that hard rock perforate is loaded down with trivial details, poor accuracy, difficulty are high, unstable;
2, first centreless drilling system in small-bore enters in hard rock, reduces large aperture core drill and enters changing of the relative positions when system contacts with hard rock and cause the change of perforate coordinate, improve the degree of accuracy of hard rock perforate;
3, the application of accessory system, reduces the deviation that drilling system own wt causes to greatest extent, reduces changing of the relative positions when drilling system contacts with hard rock further, ensure that the degree of accuracy of boring.
