Abstract
ABSTRACT
In a tool to collect Drill Grindings in the order that they were drilled so they may be analyzed to determine the outlines width length or grade of ore bodies in underground operation using pneumatic drills commonly known as Jack Legs and Long Hole machines. This invention consists of a collector box and burlap sock. The collector box is made of plate steel with rubber facings so it forms a seal when anchored to an irregular rock face, a water hose adapter for constant flushing , a tubular port with holder at bottom where grindings are collected in burlap sock and a centre drill port with rubber seal for drill steels and coupling to pass through. The burlap bag is cylindrical having a length of 1.5 metres and a width of 2 cm to 4 cm depending on the size of drill bit being used.
The basic design for the collector box can be changed to adapt to vertical drilling with a long hole machine.

Description
SPECI~IC~TIONS
II) This invention relates to a drill grinding collector for us~
in underground opera-tion.
(II) It is common practice in underground operation to drill test hole because of the erratic nature of some ore bodie~. In order to locate or explore the possibilities of adjacent ore bodies -the method commonly used is to drill with a Jack Leg (air Pneumatic drill) using extension steels and carbide bits. The worker collecting grinding in a plastic or burlap sample bag. These holes are usually in the area of 6 metres in length because the grindings collected are mixed in the sample bags they are difficult to analyze and do not give a clear picture of the ground structure. For longer hose up to 30 metres in length or in some cases more a small diamond drill is used. All through the diamond drill recover core that can be analyzed with ease it is a very slow and expensive procedure.
IIII~ I have found that by collecting drill grindings in the order that they were drilled it is possible to provide a fairly accurate reading of the structure being examined. It also permits the use of a long hole machine ins-tead of a diamond drill reducing the drilling time and cost of exploration. The burlap tube attached to the collector box receives the grinding as they are flushed from the hole being drilled with the water that the drill itself provided (as all pneumatic drill in underground operations must flush their own holes because dry drilling is not permitted in hard rock mines). These drills are also equipped with air back flush designed especially to blow grindings out of holes.
(IV) In drawings which illustrate embodiment of the invention, figure l is a side view. Drilling a hori~ontal hole with drill steel in its port. Collector box bolted to the rock face, bolts not numbered. The burlap tube in place being filled. Figure 2 is a top view of this embodiment. Figure 3 is a front view without drill steel or anchoring bolts. Figure 4 is a planned view of another embodiment having a different design so it may be attached to the slide of a long hole machine drilling a vertical hole.
The tool illustrated comprises of a steel plate collector box l which is att~ched to the rock face by anchor bolts. The rubber facing 2 i~ adjusted to the rock face by moving it back or forward in slot 3 and secured to box by nuts and bolts ~. The water tube adapter 5 is a common 90' elbow with a threaded end welded to the main body l. Better illustrated in figure 3. The drilling port 6 is a hole of 6 cm to allow drill steel and coupling to pass through collector box. The rubber seal 7 comprises of soft rubber commonly known as live rubber anchored by nuts and bolts.
The collector tube 8 is a 2.5 cm tube of l5 cm in length welded -to the bottom of collector box. The tube holder 9 are made of spring steel and attached to collector box by nuts and bolts. The collector tube 10 is made of burlap and allows water to pass through it while retaining grindings. The tubes l0 vary in sizes according to drill bit si~e being used. The collector box is secured to the drill face by 2" angel iron ll welded to collec$or box and clrilled to accept anchor bolts.
In the embodinlent shown in figure 4, the design of the collector box is changed in order to drill holes in vertical position. The box has been at-tached to the drill slide itself and only has to be set close to the drill face to get the same results as that of figure 1-3. The principal of the invention stay with same collecting grindings in the order that they are drilled.
