Abstract
A kind of method of separating marble, granite stone from ore body with detonating fuse, its principal character are for forming in each boring that the stone material parting surface laid detonating fuse to be set, and water or fine sand clog fully, are connected into an explosive fuse network.This method can evenly distribute blast on whole stone material parting surface; synchronous effect; thereby overcome the harmful effect that general drilling and blasting method causes to rock property; help the protection and the utilization of mine resources, and have reducing cost, improve work efficiency, the advantage of the big lumpiness stone material of exploitation simple to operate, safe and suitable.
Description
A kind of method of separating marble, granite stone with detonating fuse from ore body.Separate marble, granite stone from ore body at present, adopting rock sawing machinery that ore body is carried out the multiaspect cutting fully except that the minority mine forms the stone material parting surface, general using unidirectional mechanical cut surface or under the situation that has natural bedding, joint fissure adopts the jewel hole wedge to split or drilling and blasting method forms from ore body and separates necessary other parting surface of stone material.
It is exactly on the direction perpendicular to machine cuts face or natural bedding, joint fissure that the jewel hole wedge splits method, play row boring parallel to each other by certain requirement, and insert gad at the oral area of each boring, make gad with artificial bell then, make and going out a crack that connects with existing machine cuts face or natural bedding, joint fissure along boring on line direction squeeze crack: the drill eye blasting rule is the cartridge bag that setting is made by low explosive or gunpowder, incendiary agent in boring, clog with soil, the cartridge bag explosion time makes stone material separate ore body along the boring distributing line.
Try out a kind of expansion agent of perfusion in boring recently, the expansion force that produces when relying on the expansion agent aquation makes stone material separate from ore body.
Above-mentioned jewel hole wedge splits method and the expansion agent method can not cause harmful effect to stone material and ore body, but owing to separate in the ore body process at stone material, the power that acts on the whole stone material parting surface is inhomogeneous, asynchronous, causes parting surface not straight, so that the stone material yield rate reduces, and cost improves; Also be subjected to the influence of the gentle temperature of weather when using expansion agent, operation is also inconvenient.The major defect of drilling and blasting method is to have destructive crack inner generation of stone material, influences stone material quality and yield rate, is unfavorable for the protection and the utilization of mine resources, also has the unsafe shortcoming of operation simultaneously.
The object of the present invention is to provide a kind of method of separating marble, granite stone from ore body,, improve stone mining technology to overcome above-mentioned drilling and blasting method major defect with detonating fuse.
According to a kind of method of separating marble, granite stone with detonating fuse from ore body provided by the present invention, in each boring of being laid for formation stone material parting surface, detonating fuse branch greater than 15～20 centimetres of drilling depths is set, and the one end is parallel on the trunk line detonating fuse, on whole stone material parting surface, form a detonating fuse networking.
According to method of the present invention, in the boring that detonating fuse branch is set, water or fine sand filling; Also detonating fuse can be put in advance an elongated polybag of filling with above-mentioned padding, and then be set in the boring.
According to method of separating marble, granite stone from ore body provided by the present invention, when forming a plurality of mutually perpendicular stone material parting surface at the same time, can be arranged on the relative length between the trunk line detonating fuse in the detonating fuse networking on the different stone material parting surfaces by adjusting, control the moment that detonation wave arrives stone material parting surface diverse location, to obtain the optimum efficiency of stone mining.
Adopt method provided by the present invention when ore body separates marble, granite building stones, overcome the destruction that causes with common drilling and blasting method rock.Carry out resistance to compression, tension, shearing resistance, freeze the comparative illustration of 7 test datas such as molten through the grouping of more than 160 samples, method provided by the present invention can not have any impact to the quality of stone material and ore body, compare with existing method of separating stone material from ore body, also have and reduce cost, the advantage that reduces labour intensity and simple to operate, safety and be suitable for exploiting big lumpiness stone material.By the explanation of following example, characteristics of the present invention and advantage will more can be obvious.
