Description

Technical Field

[0001] The present application relates to the field of mine sampling technology, and specifically to a geological sampling device based on stope blasthole drill cuttings production and a method for using the same. Background Art

[0002] Before mining, the area where the mineral mining site is located is often sampled and tested through pre-sampling, so that the staff can grasp the expected geological grade of the ore in the mining site, predict the mining grade, and estimate the depletion rate. In the mining site sampling operation, the drill cuttings generated by the blasthole construction are often collected and sampled by using a sampling device for analysis.

[0003] For example, the Chinese invention patent with the announcement number "CN211602450U" discloses an open-pit mine blasthole ore cuttings sampler, which is achieved by inserting one end of the pipe mouth cutting foot of the split half-circular tube one and the split half-circular tube two into the open-pit mine blasthole ore cuttings, rotating the pipe joints at the other ends of the split half-circular tube one and the split half-circular tube two, and using the split half-circular tube one and the split half-circular tube two to take out the ore cuttings sample, and the buried depth of the ore cuttings in the blasthole can be judged according to the transparent ruler with scale on the split half-circular tube one and the split half-circular tube two, so that the staff does not have to dig up the blasthole cuttings pile and can take samples with little disturbance to the cuttings.

[0004] However, in the above patent, although the structure of the prior art can realize the sampling operation of blasthole drill cuttings, in the actual sampling operation of such sampling device, sampling is only performed by closing the open semi-closed circular tube one and the open semi-closed circular tube two, which is often inconvenient for the staff to conveniently grade and separately store the drill cuttings of different depths. The staff needs to perform multiple sampling operations to complete the sampling work of a single blasthole, and the sampling of blasthole debris requires the collection of blasthole drill cuttings at multiple points, which is inconvenient for the staff to perform convenient and efficient blasthole drill cuttings sampling operations.

[0030] The present application will be further described in detail below through the accompanying drawings and examples.

[0031] Reference Figure 2 、 Figure 3 and Figure 4 The embodiment of the present application provides a geological sampling device based on the production of blasthole drill cuttings in a mining area and a method for using the same, including a sampling barrel 1 and a sampling rod 2 for lifting drill cuttings. A sampling groove 101 is provided inside the sampling barrel 1, and a layered sampling cavity 3 for layered sampling of blasthole drill cuttings is integrated on one side of the inner wall of the bottom of the sampling groove 101. The layered sampling cavity 3 has multiple groups of sampling ports 301 symmetrically provided on one side of the sampling groove 101, and multiple groups of sample storage grooves 302 are provided inside the layered sampling cavity 3. The tops of the multiple groups of sample storage grooves 302 are respectively penetrated by the multiple groups of sampling ports 301.

[0032] Multiple groups of sample outlets 303 are provided outside the sampling tube 1 and the layered sampling cavity 3. The multiple groups of sample outlets 303 penetrate the bottoms of the multiple groups of sample storage tanks 302 respectively. The insides of the sample outlets 303 are hingedly connected with arc-surface sealing plates.

[0033] The sampling rod 2 includes a rod body 201 penetratingly connected to the sampling barrel 1 and a conical block 202 slidably connected to the sampling slot 101 . A sealing block 204 for sealing the sampling port 301 is provided on the surface of the rod body 201 .

[0034] The sampling rod 2 also includes a handle 203. The sampling rod 2 forms a rotating structure with the rod body 201 and the conical block 202 through the handle 203. The handle 203 is close to the conical block 202 on one side and an identification block is integrated on the conical surface. When the device is used for sampling in a blasthole in a stope, the conical block 202 at the bottom of the sampling rod 2 can assist the sampling tube 1 to penetrate into the blasthole. After the sampling tube 1 reaches the appropriate sampling depth, the rotation of the sampling rod 2 can drive the blocking block 204 to release the sealing block 204 from the sampling port 301. The seal allows the sample debris entering the sampling slot 101 to be graded and sent into the multiple groups of sample storage slots 302 from the multiple groups of sample inlets 301, so that the staff can conveniently perform graded sampling of drill cuttings at different depths. At the same time, after the sampling tube 1 is lifted and taken out, the hinged flaps in the external sample outlet 303 of the stratified sampling cavity 3 are opened in sequence, so that the staff can conveniently and separately store the blasthole drill cuttings sampled at different depths, thereby improving the efficiency of the staff in the blasthole drill cutting sampling operation.

[0035] Reference Figure 1 and Figure 3 In one aspect of the present application, a support plate 102 for hand-holding is integrally provided on the top of the sampling tube 1, and two groups of support mechanisms 4 for ground support are symmetrically provided on the bottom of the support plate 102.

[0036] The supporting mechanism 4 includes a connecting sleeve 401 and a supporting rod 402 that are sleeved and connected. A reset spring 403 is sleeved and installed inside the connecting sleeve 401. The connecting sleeve 401 and the supporting rod 402 form a telescopic structure through the reset spring 403. When the device performs sampling operations in the blasthole in the mining area, the two groups of supporting mechanisms 4 are set up to provide stable support and guidance for the sampling tube 1 when the staff is grounded for sampling, thereby improving the stability of the sampling operation of the device, and in conjunction with the telescopic setting of the connecting sleeve 401 and the support rod 402, sampling operations at different depths can be performed on the sampling tube 1.

[0037] Working principle: When using the geological sampling device based on the production of drilling cuttings from the blasthole in the mining area and the method for using the same, the conical block 202 at the bottom of the sampling rod 2 should be rotated and set at the bottom of the layered sampling cavity 3, and the sampling tube 1 should be pressed down and sent into the blasthole. During this process, the blocking block 204 on the surface of the sampling rod 2 and the sampling port 301 are sealed to prevent the debris from entering the layered sampling cavity 3 during the pressing process. In addition, the conical block 202 at the bottom of the sampling rod 2 and the grounding support of the two sets of support mechanisms 4 can assist the sampling tube 1 in guiding and penetrating different depths inside the blasthole. When the device is sampling, the sampling rod 2 is rotated to drive the sealing block 204 to release the seal on the sampling port 301, so that the sample debris entering the sampling tank 101 can be sent from the multiple groups of sampling ports 301 to the multiple groups of sample storage tanks 302 in a graded manner, so that the staff can conveniently perform graded sampling of drill cuttings at different depths. After the device is used for sampling and storage, the sampling tube 1 can be pulled out, and the hinged flap in the external sample outlet 303 of the stratified sampling cavity 3 can be opened in sequence, so that the staff can conveniently and separately store the drill cuttings sampled at different depths.
