Abstract
The method for estimating the volume of the irregular-shaped massive ore rocks comprises the steps of randomly grabbing a certain amount of small ore rocks in the production flow of a mine; by lengthThe measuring instrument measures the three-dimensional size of each ore, the size of the largest direction of the small ore is taken as the length a during measurement, and a two-dimensional measuring size vertical to the length is determined by a method of external cutting of a cuboid, so that two-dimensional sizes b and c are obtained; and (3) calculating the volume of the circumscribed cuboid: vdAbc; then accurately measuring the actual volume V of the small ore by a discharge volume methods(ii) a By measuring volume VdActual volume VsObtaining their conversion factor, K ═ Vs/Vd(ii) a The same determination or estimation is made for the volume of irregularly shaped bulk rock using this coefficient. The invention can measure the three-dimensional size of the large ore and accurately estimate the actual volume; the determination can be carried out at any time and any place without complex process and harsh conditions; and the method can be quickly estimated, and meets the requirements of production practice.
Description
One, technical field
The invention belongs to the mining technique field, is the method for a kind of estimation irregular-shape bulk stone (or rock) volume, is applicable to the lower various dissimilar ore deposit rock of water-intake rate is carried out volume estimation.
Two, background technology
The mine often needs to measure the boulder yield index when selecting the driling explosion parameter, and by analyzing, judge that the boulder yield height is optimized the driling explosion parameter, finally determines the rational driling explosion parameter of using in the production run of mine.
Normally, measure irregular-shape bulk stone (or rock) and be difficult to calculate more accurately, preferably ore is inserted in the liquid, measure its volume.By Archimedes' principle as can be known, the volume of discharged liquid is the volume of lump ore (or rock).Though adopt this method can measure irregular ore (or rock) more exactly, it is very inconvenient to operate.With the method is unpractical: complex procedures, efficient are extremely low.
Three, summary of the invention
The present invention seeks to: propose a kind of method that can estimate fast more again that irregular big lump ore rock mass is long-pending, be convenient to the mine and measure the volume of ore (or rock) after the back production explosion, and calculate the boulder yield index, and have higher precision, provide foundation thereby optimize the driling explosion parameter for the mine.
The present invention adopts the three-dimensional dimension of actual measurement fritter ore (or rock) to calculate its circumscribed rectangular parallelepiped volume, and adopts immersed method to measure volume, is about to it and inserts its actual volume of mensuration in the liquid, finds out both conversion relations, promptly tries to achieve both reduction coefficients.According to the principle of similitude,, especially, just can finally accurately calculate the volume of bulk as long as survey three sizes by measuring the three-dimensional dimension of the circumscribed rectangular parallelepiped of lump ore (or rock).
The present invention estimates that the step of rock volume and method are:
1) in the production procedure of mine, grasps a certain amount of fritter ore at random;
2) adopt length-measuring appliance to measure the three-dimensional dimension of each lump ore stone, when tolerance with the size of the maximum direction of fritter ore as length a, determine the two-dimensional measurement size vertical with the method for circumscribed rectangular parallelepiped with length, obtain two-dimentional two size b, c;
3) two sizes according to length and two dimension calculate its circumscribed rectangular parallelepiped volume (the present invention claims to measure volume) V
d=abc;
4) according to Archimedes' principle, these fritter ores are submerged in the liquid, the volume of measuring its discharged liquid is the actual volume V of fritter
S
5) by tolerance volume V
d, actual volume V
SObtain their reduction coefficient, K=V

6) the three-dimensional dimension V of irregular-shape bulk rock volume

S=KV
d=Kabc.
The present invention chooses length direction is vertical therewith a cross section as two-dimensional measurement face, obtains two size b, c of two dimension; The inventive method is generally chosen the maximum secting area place and is measured wide and high two-dimensional;
The present invention is based on such understanding: for certain specific mine, no matter ore fragmentation is greatly or little, the shape of ore is similar (being the principle of similitude).Therefore, can estimate its actual volume by the three-dimensional dimension of measuring lump ore, computing formula is V
S=Kabc.
1, the technology of the present invention characteristics
Three-dimensional dimension by the tolerance lump ore can be estimated its actual volume more exactly; Mensuration work can be carried out whenever and wherever possible, does not need complicated process and exacting terms; Can estimate fast that again irregular big lump ore rock mass is long-pending, satisfy need of production practice.
Four, embodiment
Adopt clamp (or other measurement instruments) to measure the three-dimensional dimension of each lump ore stone during fritter ore tolerance, when tolerance with the size of the maximum direction of fritter ore as length, and measure in addition two-dimensional of its circumscribed rectangular parallelepiped with this, generally get the maximum area place and get wide, high size.Calculate its circumscribed rectangular parallelepiped volume (the present invention claims to measure volume) V according to three-dimensional dimension
dCalculate the ratio of three-dimensional dimension.And be categorized into the rectangular parallelepiped of various segmentations according to this, they are divided into platypelloid type, approximate cubic type, pure rectangular build (adopting when permissible accuracy is higher) obtain different K value spans.
According to Archimedes' principle, these fritter ores are submerged in the liquid, the volume of measuring its discharged liquid is the actual volume V of fritter
S
By tolerance volume V
d, actual volume V
SObtain their conversion relation, K=V
S/ V

Through the calculating of a certain amount of fritter ore, the span of K is about 0.4-0.55, and K value commonly used gets 0.5.
As a bulk of ore of typical measurement, long 0.8 meter, wide 0.73 meter, high 0.74 meter, calculate V
dEqual 0.43216 cubic metre, the K value is got 0.5 o'clock then V
SBe 0.216 cubic metre, survey also identically, meet finely.Shape such as platypelloid type, taper will be got 0.4-0.45 with the K value and comparatively be met.
Meishan iron mine is prominent domestic large-scale underground mine, and year ore productive capacity is more than 3,000,000 tons.In the past few decades, no matter the mine generally, changes which parameter in the parameters such as blasthole diameter, burden, explosive having carried out repeatedly improvement aspect structural parameters, the driling explosion parameter, all will demarcate the explosion situation.By staking-out work, grasp the composition of various grades, and parameter is optimized adjustment according to the boulder yield height.
When measuring the bulk volume, we have adopted irregularly shaped ore (or rock) volume method of estimating cost, have satisfied the needs that mining is produced.Facts have proved: this technical matters is simple, practical, implements also to have certain precision easily, and be applicable in the field, mine at home.
