Abstract

The utility model discloses a kind of protector that stops explosion Rolling Stone, it is by row's rigid support (4), Rolling Stone protective screening (5), fixedly anchor cable (6), short anchor pole (7) constitute; Described rigid support (4) is fixed on slope rock mass (1) domatic; Rolling Stone protective screening (5) adopts fixation with steel wire upper in rigidity pillar (4), and Rolling Stone protective screening (5) is positioned at upward slope direction one side of rigidity pillar (4); Fixedly one end of anchor cable (6) is connected with rigidity pillar (4), and fixedly the other end of anchor cable (6) adopts short anchor pole (7) to be fixed in slope rock mass (1), and fixedly anchor cable (6) is tension-like; Described Rolling Stone protective screening (5) is to consist of reinforced mesh overlap joint.The utility model can stop rockfall safely and effectively, avoids the generation of explosion Rolling Stone hazardous accidents, creates good operating environment, can improve ore recovery ratio simultaneously, reduce ore losses amount, increase substantially mine production safety, create good economic benefit and social benefit.

Description

A kind of protector that stops explosion Rolling Stone
Technical field
The utility model relates to a kind of Rolling Stone interception, retention device, interception, the protector of explosion Rolling Stone while especially relating to outdoor abrupt slope blast working, in the engineering explosion in mine and other fields, non-mine, be used for preventing the harm of explosion Rolling Stone in the open, realize safety blasting.
Background technology
Fast development along with China's economic construction, China's part surface mine moves towards the edge in village, cities and towns just gradually, mine blasting environment is become increasingly complex, explosion harm risk constantly increases, directly affect mine living and working in peace and contentment of the common people around, when wherein abrupt slope opencut is by side exploitation, explosion Rolling Stone is a Major Risk Factors, if it can not be effectively controlled, very easily cause shotfiring safety accident, threaten the safety of life and property of the common people and enterprise, seriously restricting the safety and high efficiency of enterprise.
After Rolling Stone refers to top layer sillar on hillside or explosion, sillar starts to move downward from slope surface under the disturbance of various natures or human factor, through sliding, collision, tiltedly throw or one or more motion modes combinations of rolling after, finally in relatively low gesture place because of the process that kinetic energy disappears under static.When causing, the motion of Rolling Stone the direct or indirect loss of human life and property formed Rolling Stone disaster.
When exploit by side on the abrupt slope under complex environment, the direction of fall on abrupt slope is generally village, cities and towns, farmland etc.Be generally the generation of avoiding Rolling Stone accident, guarantee the production safety of enterprise, stope around often stays and establishes certain side slope resource and will not exploit in the open, caused ample resources waste, increased ore loss ratio, directly reduced the economic benefit in mine, Ye Yu China related resource extraction system Laws & Regulations is disagreed.
Summary of the invention
For effectively controlled blasting Rolling Stone harm, create good operating environment, the utility model provides a kind of protector that stops explosion Rolling Stone.This device can stop rockfall safely and effectively, and the security incident of avoiding Rolling Stone landing to cause improves ore recovery ratio, reduces ore loss ratio, increases substantially mine production safety, creates good economic benefit and social benefit.
For realizing above-mentioned purpose of the present utility model, the utility model is a kind of stops that the technical scheme of the protector employing of explosion Rolling Stone is:
The protector that the utility model is a kind of stops explosion Rolling Stone is by row's rigid support, Rolling Stone protective screening, fixedly anchor cable, short anchor pole constitute.Described rigid support is fixed on slope rock mass domatic; Rolling Stone protective screening adopts fixation with steel wire on rigidity pillar, and Rolling Stone protective screening is positioned at upward slope direction one side of rigidity pillar; Fixedly one end of anchor cable is connected with rigidity pillar, and fixedly the other end of anchor cable adopts short anchor pole to be fixed in slope rock mass, and fixedly anchor cable is tension-like, prevents the stability of Rolling Stone impact failure rigidity pillar.
Described Rolling Stone protective screening is to consist of reinforced mesh overlap joint, and adjacent steel mesh reinforcement oblique cut grafting length >=20cm, is generally 20-30cm.During adjacent steel mesh reinforcement oblique cut grafting, guarantee to overlap quality.
The suitable size of described reinforced mesh is 2m * 2m, and the size of mesh be take the diamond-shaped meshes of 20cm * 20cm as good.
The utility model is a kind of stops that the protector of explosion Rolling Stone adopts after above technical scheme, there is following effect: can stop safely and effectively rockfall, avoid the generation of explosion Rolling Stone hazardous accidents, create good operating environment, can improve ore recovery ratio simultaneously, reduce ore losses amount, increase substantially mine production safety, create good economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is a kind of protective device structure scheme of installation that stops explosion Rolling Stone of the utility model.
Reference numeral is: 1-slope rock mass; 2-blasting excavation region; 3-reserved stone dam; 4-rigidity pillar; 5-protective screening; 6-fixing anchor cable; 7-short anchor pole.
The specific embodiment
For further describing the utility model, below in conjunction with accompanying drawing, to the utility model is a kind of, stop that the protector of explosion Rolling Stone is described in further detail.
The utility model is as shown in Figure 1 a kind of stops that the protective device structure scheme of installation of explosion Rolling Stone finds out, the protector that the utility model is a kind of stops explosion Rolling Stone is by row's rigid support 4, Rolling Stone protective screening 5, fixedly anchor cable 6, short anchor pole 7 constitute.Blasting excavation region 2 adopts loosening Millisecond Controlled Blasting technology.In the side slope near explosion boundary region, leaving is highly the reserved stone dam 3 of 3m, and reserved stone dam 3 one sides are natural slope, and opposite side angle of inclination is controlled at 75 °, and this reserved stone dam 3, as the Rolling Stone barricade in blasting excavation region 2, prevents explosion backlash.After 2 back production of blasting excavation region finish, near reserved stone dam 3 places, adopting hydraulic breaking hammer to carry out break process, to alleviate the damage and fracture of bursting work to reserved stone dam 3.Below reserved stone dam 3, the setting of 1m place is highly the Rolling Stone protective screening 5 of 2m together.Rolling Stone protective screening 5 is to be formed by the reinforced mesh overlap joint that is of a size of 2m * 2m, mesh is the diamond-shaped meshes of 20cm * 20cm, adjacent steel mesh reinforcement oblique cut grafting length is 20cm, every 3m, rigidity pillar 4 that a diameter is 10cm is set with fixing Rolling Stone protective screening 5, Rolling Stone protective screening 5 is positioned at upward slope direction one side of rigidity pillar 4; The length 2.5m of described rigidity pillar 4, bottom 0.5m is embedded to the domatic upper of slope rock mass 1, adopts concreting to fix; Fixedly one end of anchor cable 6 is connected with rigidity pillar 4, and fixedly the other end of anchor cable 6 adopts short anchor pole 7 to be fixed in slope rock mass, to improve the stability of rigidity pillar 4; Fixedly the diameter of anchor cable 6 is Φ 12mm, and the length of short anchor pole 7 is 0.5m.Fixedly anchor cable 6 will be strained, and prevents the stability of Rolling Stone impact failure rigidity pillar 4.Rolling Stone protective screening 5 and reserved 3 two safeguard procedures of stone dam in top, play dual intercepting effect, greatly strengthened the protection effect of explosion Rolling Stone.
