Description

Gan Nan bores---and manpower impacts auger

Technical field

The present invention relates to geological prospecting field, is a kind of exploration prospecting means of weathering crust type mineral deposit, is specially adapted to the Prospecting and evaluation that weathering crust ion adsorption type rare earth ore produces; Be on the basis of Luoyang Spade, update and innovation, and the one mine locating auger grown up.

Background technology

In the geologic prospect process of Rare Earth Mine, traditional Luoyang Spade exploration means has certain limitation: cannot expose ore body when ore body thickness is large, fail to reach the defects such as sampling object.Accuracy is sampled, in actual mechanical process in the wild, by having updated with perfect invention Gan Nan brill with raising in order to reach sampling object.This novel mine locating auger has low consumption, safety, environmental protection, efficiency high, can not only ensure not by other material union dyeing in the process sampled, and can also determine the position of sampling accurately.

Summary of the invention

The present invention is on the basis of Luoyang Spade, updates and innovation, and the one mine locating auger grown up.Be characterized in that low consumption, safety, environmental protection, efficiency are high.

Gan Nan bores structure simply, primarily of drill bit, rock core dropping against device, drilling rod, catcher, operating rod composition:

Drill bit: be made up of the edge of a knife, sampler barrel, drill bit welding muscle, different diameter joint.

The edge of a knife: be connected as a single entity with sampler barrel is drill bit lower part, high 200mm, and the edge of a knife is horn-like, conventional three kinds of specifications (see table 1).

Sampler barrel: be stainless-steel tube, long 200mm, 300mm, 400mm, three kinds of specifications, wall thickness 2mm, three kinds of specifications (see table 1).

Drill bit welding muscle: the reinforcing bar be connected with reducer union for sampler barrel upper end.

Different diameter joint: be reducer union.

Rock core dropping against device: be stainless steel ware, high 50mm, three kinds of specifications (see table 1), during for pulling out of hole, prevent hole wall rock core from falling at the bottom of hole.

Drilling rod: drilling rod is galvanized conduit (mark material), diameter 33mm, length 2m/ root.

Joint: the company's part between drilling rod and drilling rod.

Operating rod: the topmost portion drilling rod that workmen grasps, be generally common drilling rod, also can make drilling rod (outsourcing 1 ~ 2mm rubber) with light firm material, length is 2m or 3m.

South, the table 1 Jiangxi auger edge of a knife, sampler barrel, rock core dropping against device three kinds of specification units are millimeter

Probing bore is the most basic regulation of geological drilling engineering, and the representativeness of foundation weathering crust geologic feature and collected specimens, for reaching sampling object, Gan Nan bores basic bore and is defined as 95mm, 80mm or 76m.

Gan Nan bores drilling depth and rock completely decomposed layer thickness, hardness is relevant, and general completely decomposed layer thickness is no more than 45m, therefore, determines that the southern drilling depth in Jiangxi is within 45m.

According to drilling technology, Gan Nan bores and is applicable to rock grade I ~ II level.Its characteristic (see table 2).

Table 2 I ~ II rock grade characteristic

Accompanying drawing explanation

Figure 1 shows that Gan Nan bores structural representation, wherein 1 is the edge of a knife; 2 is sampler barrel; 3 is drill bit welding muscle; 4 is different diameter joint; 5 bleed off device for rock core; 6 is drilling rod; 7 is joint; 8 is operating rod; 9 is rubber.Figure 2 shows that the sampler barrel of long 200mm, wherein 1 is the edge of a knife; 2 is sampler barrel; 3 is drill bit welding muscle; 4 is different diameter joint.Figure 3 shows that the sampler barrel of long 300mm, wherein 1 is the edge of a knife; 2 is sampler barrel; 3 is drill bit welding muscle.Figure 4 shows that the sampler barrel of long 400mm, wherein 1 is the edge of a knife; 2 is sampler barrel; 3 is drill bit welding muscle.

Embodiment

The work progress that Gan Nan bores, comprise determine position, hole → simple and easy smooth location → preparatory stage → perforate creeps into → rock core arrangement → curtailed sampling → whole hole → correction hole depth → sealing of hole → examination.

The working specification that Gan Nan bores mainly comprises:

Gan Nan wants vertical ground to tunnel downwards when boring perforate driving, will carry out displacement driving when meeting horsestone or weathering ball.

In work progress, drilling tool slowly must be put at the bottom of hole when boring under every round trip, the causing hole cinclides heart of avoiding occurring with hole wall rubbing is fallen at the bottom of hole, causes rock core union dyeing.During general sampling, union dyeing rock core in sampler top is rejected.

In work progress, each round trip tunnelling footage must not be greater than the length of the bit (being generally 0.20m ~ 0.40m), when carrying brill, is slowly mentioned by drilling tool, in case rock core drops out in sampler barrel.

Drilling depth General Requirements, through ore body, is namely exposed completely decomposed layer, is entered half waste mantle 1m (being not less than 0.5m) whole hole afterwards.

Construction adopts and creeps into without washing fluid.

The sample collection that Gan Nan bores is as described below:

Gan Nan bores fundamental analysis sample collection method and adopts rock core division method.

Prevent sample contamination, when every round trip is cored, must check whether drill bit top has rock core union dyeing, can distinguish from color and ground loosening degree, rock core will be mixed and reject.

Boring fundamental analysis sample is taked by different layers position and different ore type, and basic sample is long is generally 1m.

Rock core division method: first puddle evenly to the rock core in same fundamental analysis sample at the scene, then adopts diagonal method to carry out division, repeats for several times, until meet sample presentation standard, finally institute's coring is divided two sample pack numberings.One is sent laboratory to analyze, and another duplicate sample is made rock core and preserved so that for future reference, and the weight after each sample splitting should be greater than 2.00Kg.Require in sample splitting process that rock core is puddled evenly, operation carefully, ensures sample quality.

Sample number into spectrum is encoded by ' job number+sampfe order number ', each engineering number consecutively in order.

Example weight after sample number into spectrum, sample length, sample original weight, division number of times and division all should record clear in time on the spot, insert in sample registration form.

Sample processing and test are strictly pressed code requirement and are performed.
