Description
Technical field
The utility model belongs to a kind of stone mining technology and equipment, particularly a kind of static blasting technology and equipment.
Background technology
Static crushing method (static blasting technology) is a kind of fragmentation (or cutting) rock and the concrete new method that grows up nearly period, also claims static(al) to compel to split and the Static crushing technology.Exactly, it is the static blasting chemical method.Its basic principle, foundation are: general rock or concrete all belong to fragile material, and the compression strength of fragile material is big, and tensile strength is little, and its tensile strength is much smaller than compression strength.The tensile strength of rock is 4-10Mpa, and the about 1.5-3.0Mpa of concrete tensile strength is equivalent to the 1/10-1/20 of its compression strength approximately.And the bulbs of pressure of static breaking agent can reach 30-50Mpa usually.So reasonably broken design (determining of explosive payload, aperture, hole depth and pitch of holes) is to make eyelet medium on every side be subjected to fully destroying.As long as constraint exists, cracking agent just has and continue to produce or residual to a certain degree the character of the bulbs of pressure, thereby can continue increase or produce new crack.
In the present stone mining, mainly adopt the static blasting chemical method.It is by uniform brill one round of certain spacing according to line of cut, then with a kind of molybdenum that contains, magnesium, calcium, the Powdered static breaking agent of the inorganic salts of elements such as titanium, with the mobile shape slurry of suitable quantity of water furnishing, directly pour in the boring, hydration reaction by expension-spalling agent generation in boring, make crystal modification, growth volume in time increases, produce the bulbs of pressure (radial compressive stress and hoop tension), lentamente, impose on hole wall quietly, after after a while, reach maximum, produce at its chemical reaction under the effect of the huge bulbs of pressure, rock is cracked by the line of cut of setting, thereby obtain the method for the stone material blank of suitable production and processing.(so-called stone material blank is the building stones that possess the certain size size that exploitation obtains from the mine, and it is the raw material that processing stone sheet material, section bar, engraving, sculpture are used)
There is, fill up expension-spalling agent after, rock generally takes 1-3 days and just can split, efficient is low; Poor effect when temperature is low, during near 0 ℃, expension-spalling agent stops chemical reaction, can't use; Expension-spalling agent is an expendable consumed product, and the expension-spalling agent consumption is big, waste resource, production cost height; The deficiencies such as residue contamination environment that produce.
Adopt keyword to Chinese patent and authoritative website retrieval and market survey, find 1 of the relevant patent of static blasting chemical method, it is that Wuhan Polytechnical Univ applies in the woods ancestor longevity, and the patent No. is 87207860 patented technology; Do not find and hydraulic static blasting method relevant report of the present invention and product.
