Description
Technical field
The present invention relates to a kind of thermal expansion stone cracking agent equal proportion structure large area to split cubic meter of stone method, belongs to Materials Science and Engineering
Technology crossing domain.
Background technology
Commercial explosive occupies leading position in mine excavation always in the past, but because generally existing labor intensity is big, work
The shortcomings of imitating low, waste of resource, security difference and pollution environment, in addition to except part, engineering still needs commercial explosive, industry is fried
Medicine is gradually substituted by stone cracking agent.Stone cracking agent because with it is noiseless, controllable, without chip, financial cost it is low, using simple, construction and
The advantages that transportation safety, protection resource and environment, and it is widely used in building stones cutting, catalase, the cutting of groove open caisson, concrete
The engineering constructions such as basis dismounting, play increasingly important function in the development of the national economy.
A new varieties of the thermal expansion stone cracking agent as stone cracking agent product, more heat transfer is discharged by chemical reaction, heat
High temperature caused by amount release can heat and destroy surrounding medium, and caused portion gas is due to high-temperature heat expansion effect and to week
Enclose medium acting.Due to produce gas flow it is few, be merely capable of being formed the extremely weak bulbs of pressure and decline of pressure quickly, be merely able to
Several meters of closely interior effectively acting.Thermal expansion stone cracking agent caloric value is big, and acting scope is small, can be answered in many fields
With, such as its action effect is far away from engineering explosion, but action effect is much better than stone cracking agent, the rock that is particularly suitable for use in, concrete,
The fast and safely cracking of bridge pier, building etc..
With development in science and technology and social progress, resources conservation, efficient construction concept are gradually paid attention to by industry personage.Due to
The standard for judging that neither one is theoretical of the amount of stone cracking agent needed for counterincision stone, cause stone cracking agent blindly to drill in use,
Blindness powder charge, so that dose deficiency, the excessive phenomenon of dose emerge in an endless stream in use, stone cracking agent is caused huge
Waste, this is gradually paid attention to by workmen.
Therefore, foundation can instruct the appraisal procedure of thermal expansion stone cracking agent medicament usage amount in the case of difference splits stone very
It is important.
The content of the invention
The invention aims to solve stone cracking agent in use blindly drilling, powder charge and stone cracking agent is caused huge
Big the problem of wasting, there is provided a kind of thermal expansion stone cracking agent equal proportion structure large area split cubic meter of stone method.
The purpose of the present invention is achieved through the following technical solutions.
A kind of thermal expansion stone cracking agent equal proportion structure large area splits cubic meter of stone method, comprises the following steps that:
Step 1: it is 2R to choose size dimension0Square stone, it is h that depth is drilled through in stone center0Hole, dress
Stone cracking agent is filled out, carries out splitting stone experiment, screens optimal boring radius r0;
The optimal boring radius r of screening0Method is:Drill through minimum boring radius r1, load thermal expansion stone cracking agent and split
Stone is tested, and expands boring radius r successively1Value, until reaching optimal splits stone effect, i.e., rock being capable of instant of complete cracking and needed for reaching
The displacement wanted, boring radius value now is r0;
Step 2: ensure identical standard split stone in the case of, it is determined that intend cracking stone drilling plane S, according to construction
It is required that drill center distribution determine spacing of wells d;Measure at drill center perpendicular to the rock thickness h of drilling plane1, then bore
Hole depth h isBoring radius r is r=(d × r0)/2R0;
Step 3: the h and r according to obtained by step 2 is drilled, thermal expansion stone cracking agent is loaded into drilling and carries out splitting stone;
The step 1 R0、h0Taken unit is rice, works as R0Span be more than 1 meter when, drill through depth
Rice;Work as R0Value be less than or equal to 1 meter when, drilling through depth isRice;
The step 2 identical standard splits stone situation for required cracking stone material is identical, thermal expansion stone cracking agent kind batch
Temperature environment that secondary identical, stone cracking agent uses is identical, surrounding space medium residing for cracking stone is similar;
The step 2 determines the drilling plane S of plan cracking stone, and specific method is:Easy construction platform face is unique, chooses
Easy construction platform is as drilling plane;In the case of easy construction platform is not unique, chooses the maximum plane of two-dimensional directional stretching, extension and make
For drilling plane;
Beneficial effect
