Abstract
The invention provides a method for passing through a total rock section in a coal mining process. The method comprises the following steps: firstly, one measure roadway with the length of 5m is constructed on the part, located on the total rock section, of a coal wall of a ventilation roadway every 10m; the tail ends of all the measure roadways are communicated by a communication roadway; when the stoping is carried out on a working surface until the distance to the total rock section is 10m, a shaking hole is constructed in the measure roadways towards a working surface so as to carry out blasting treatment; and finally, single columns are arranged in the measure roadways so that roofs in the roadways are complete. According to the method, a rock roadway in the working surface can be dug in advance by constructing in the measure roadways in the total rock section; in the stoping process, the quantity of the holes in the working surface is greatly reduced, the hidden dangers to the roofs by great amount of blasting are avoided, and the loss of units and the like is reduced; and the damages to equipment by blasting are reduced, the propelling speed is enhanced and the unit yield is guaranteed.
Description
Technical field
The present invention relates to Coal Mining Technology field, specifically in a kind of seam mining process, cross the method for total rock section.
Background technology
Carboniferous System coal mining geology complicated condition, washes away, principal element that the geological structure such as karst collapse col umn, tomography is restriction per unit area yield ability.At present, crossing the conventional method that geological structural belt takes is the mode adopting vibrations big gun, but which fltting speed is slow, serious to device damage, and ubiquity 0.8 ~ 1.5 meter of coal seam alternating layers above Taiyuan seam group, put roof control difficulty when shaking big gun, be therefore badly in need of a kind of quick, safe method of tackling key problem and carried out geological structural belt.
Summary of the invention
The object of the invention is to solve above-mentioned problems of the prior art, and a kind of method crossing total rock section in seam mining process is provided.
The present invention is achieved through the following technical solutions:
The method of total rock section is crossed in a kind of seam mining process, comprising the steps: 1) part that is positioned at total rock section on the rib of return airway constructs every 10m the measure lane of a long 5m, the specification in measure lane is high 3.5m, wide 3m, an end tunnel UNICOM of UNICOM in all measure lanes; 2) after the construction of measure lane, when working face extraction is to distance total rock section 10m place, to work plane direction construction vibrations eye in measure lane, implement shallow blasting, be specially: utilize air rock drill on the wall of lane, measure lane, beat two rows vibrations eye, wherein, two rows shake the distance that the distance that the distance of eye is 1000mm, upper row shakes eye distance measure lane top board is 1000mm, lower row shakes eye distance measure lane base plate is 1000mm; Often in row's vibrations eye, the distance of two adjacent vibrations eyes is 1500mm, and the aperture of vibrations eye is 42mm, and the degree of depth of vibrations eye is 2m, and the explosive payload of each vibrations intraocular is no more than 500g, and the sealing clay length of each vibrations intraocular is not less than 500mm; Two rows vibrations eye is that three presbyopia are arranged, number of times of blowing out is 10 one batch of big guns; 3) after explosion, in measure lane, install monomer column, guarantee that lane inside ceiling panel is complete.
Further, when working face extraction is to total rock section, as rock still hard unit cannot be passed through time, carry out local again to drill and blast and to shake rock, be conducive to back production, be specially: at 3#-10# frame, often arrange support and make a call to three rounds, spacing 1000mm, utilizes air rock drill to punch equally.
In the inventive method, the rock gangway in work plane can be excavated in advance in total rock section working measure lane, work plane perforating number is greatly reduced during back production, avoid the hidden danger of blowing out in a large number and bringing to top board, decrease unit equal loss, reducing because blowing out the damage brought to equipment, accelerating advance rate, ensure that per unit area yield.The inventive method is compared and is taked the conventional method of putting vibrations big gun at work plane, and the time that can shift to an earlier date half is excessively complete, creates favourable guarantee for producing; The inventive method is combined to adopt and is cut about 1000 tons, rock less, greatly reduces the wearing and tearing to equipment.

Fig. 1 is the construction schematic diagram of the inventive method.
Fig. 2 is the layout schematic diagram shaking eye in the inventive method.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, 2, the method of total rock section is crossed in a kind of seam mining process, comprising the steps: 1) part that is positioned at total rock section on the rib of return airway constructs every 10m the measure lane of a long 5m, the specification in measure lane is high 3.5m, wide 3m, an end tunnel UNICOM of UNICOM in all measure lanes; 2) after the construction of measure lane, when working face extraction is to distance total rock section 10m place, to work plane direction construction vibrations eye in measure lane, implement shallow blasting, be specially: utilize air rock drill on the wall of lane, measure lane, beat two rows vibrations eye, wherein, the distance d of two rows vibrations eye
1for 1000mm, upper row shake the distance d of eye distance measure lane top board
2for 1000mm, lower row shake the distance d of eye distance measure lane base plate
3for 1000mm; Often in row's vibrations eye, the distance d of two adjacent vibrations eyes
4for 1500mm, the aperture of vibrations eye is 42mm, and the degree of depth of vibrations eye is 2m, and the explosive payload of each vibrations intraocular is no more than 500g, and the sealing clay length of each vibrations intraocular is not less than 500mm; Two rows vibrations eye is that three presbyopia are arranged, number of times of blowing out is 10 one batch of big guns; 3) after explosion, in measure lane, install monomer column, guarantee that lane inside ceiling panel is complete.
When working face extraction is to total rock section, as rock still hard make unit cannot by time, then carry out local and drill and blast rock shaken, be conducive to back production, be specially: at 3#-10# frame, often arrange support and make a call to three rounds, spacing 1000mm, utilizes air rock drill to punch equally.
