Abstract
The invention relates to an underground small-size sloping way construction method for mines, which comprises the following steps: firstly, lifting 1.7 to 2 m of a horizontal section of a construction sloping way laneway from a laneway bottom plate at one side of an ort laneway for manual slag tapping; lifting 1.1 m of a construction scraper cave chamber at the other side of the ort laneway for installing a scraper; then, erecting a simple chute at an outer opening of the horizontal section of the sloping way laneway; thirdly, carrying out gradient change blasting construction from a gradient change point at the end of the horizontal section of the sloping way laneway; using the scraper for scraping blasted rocks into the simple chute, and directly loading the rocks into a mine car to be transported away; and fourthly, blasting and transporting away scraping passage rocks from the gradient point to the bottom plate of the ort laneway. When the method of the invention is adopted, the efficiency of the small-size sloping way digging construction can be obviously improved, the production efficiency is improved from the original manual rock transportation of 2 m/d to the current scraper rock transportation of 3 m/d, and the efficiency is improved by 50 percent.
Description
Technical field the present invention relates to a kind of ramp job practices, specifically, is a kind of underground small-size sloping way construction method for mines.
Background technology in small-sized ramp (long * is wide to be 2.8m*2.8m and the following) work progress, is subjected to the restriction of span length and height under mine, can't use relatively large number shovel fortune equipment.If adopt 1m
3Diesel LHD below reaching shovels pretends industry, limited by only operation, and diesel LHD discharge tail gas pollution is bigger, and operating environment is relatively poor; If adopt 1m
3Electric LHD below reaching shovels pretends industry, is subjected to the restriction of electric LHD climbing capacity, and the efficient of carrying rock is lower.Therefore, the a dead lift rocks that adopt when construction small-sized ramp more, but constructor's labour intensity is bigger, and extension with ramp construction length, the ventilation degradation, and be subjected to transportation range and far wait conditionality, workman's operating environment variation, labour intensity increase, production efficiency decreases, and has seriously restricted the raising of production capacity.
Summary of the invention problem to be solved by this invention provides a kind of underground small-size sloping way construction method for mines, utilize scraper rapid construction small-sized ramp, use the scraper mine car of packing into of slagging tap, effectively alleviate labor strength, improve the efficient of excavation work.
Technical scheme provided by the invention is:
A kind of method of utilizing scraper rapid construction small-sized ramp, it is characterized in that: job practices may further comprise the steps:
(1), raises 1.7～2 meters construction ramp tunnel horizontal segments in a side in Chuan Mai tunnel from roadway floor, ramp tunnel horizontal segment base plate is according to 10 meters long of horizontal direction constructions, the long back of horizontal segment top board level construction 4～6m, ramp tunnel becomes the construction of position, slope, the height of tunnel horizontal segment is 1.7～2.0 meters, manually slags tap;
And raise 1.1 meters construction scraper chambers at the opposite side in Chuan Mai tunnel, the construction specification is that 1.4 meters high 2 meters of * of 2 meters wide * are long, at the scraper chamber 15KW scraper is installed;
(2), the horizontal segment collar extension sets up simple and easy chute in the ramp tunnel, its chute base plate and ramp roadway floor keep same level;
(3), begin to become position, slope blast working, and with the base plate of tunnel, slope horizontal segment rake road, use scraper will be quick-fried to descend rock to harrow in the simple and easy chute, and the mine car of directly packing into is transported as scraper from the knick point of the ramp tunnel horizontal segment end;
(4), knick point is transported to the rake road rock blasting of wearing between the arteries and veins roadway floor.
Good effect of the present invention is:
(1) obviously improve small-sized incline boring efficiency of construction, production efficiency is brought up to the 3m/d of present scraper haulage rock by the 2m/d of original artificial haulage rock, and efficient has improved 50%.
(2) effectively reduce the operation number, obviously improve workman's operating environment and labour intensity, the workman only needs 1 people to be sitting in the control of scraper chamber just can harrow the slag operation, reduces by 2～3 people than former operating personnel; Personnel directly do not arrive operation under the quick-fried talus down simultaneously, and safety also improves greatly; Adopt mechanical work, labor strength also alleviates.
(3) obviously reduce operating cost,, reduce by 20 yuan/m than the manual work cost owing to adopt electromechanical work
3, (length is by 100 meters, and section is pressed 6m for every ramp
3Calculate) but 12000 yuan of cost savings, and overall economic efficiency is fairly obvious.
Description of drawings Fig. 1 is the schematic diagram of the small-sized incline boring construction of the present invention;
Fig. 2 is the I-I cross-sectional schematic of Fig. 1.
The specific embodiment is further described the present invention below in conjunction with drawings and Examples.
Shown in Fig. 1-2, a kind of underground small-size sloping way construction method for mines, step is as follows:
(1), raises 1.7～2 meters construction ramp tunnel horizontal segments in a side in Chuan Mai tunnel 2 from roadway floor, raise highly preferred 1.8m, described ramp tunnel horizontal segment base plate is according to 10 meters long of horizontal direction constructions, become the construction of position, slope after top board 10 levels construction 4～6m is long again, walk for ease of the pedestrian, the height of tunnel horizontal segment is 1.7～2.0 meters, manually slags tap; And raise 1.1 meters construction scraper chambers 1 at the opposite side in Chuan Mai tunnel 2, the construction specification is that 1.4 meters high 2 meters of * of 2 meters wide * are long, adopts expansion type rock bolt to install 15KW scraper 12 at scraper chamber 1.
(2), set up simple and easy chute 11, its chute base plate and ramp roadway floor keep same level at ramp tunnel horizontal segment collar extension; 1.2 meters wide of simple and easy chute 11 collar extensions, 1.6 meters of internal orifices are wide, are convenient to ore concentrated harrow in the mine car 3.
(3), the knick point 9 from the ramp tunnel horizontal segment end begins to become position, slope blast working, and with the base plate of tunnel, slope horizontal segment rake road 5 as scraper 12, the pulley 7 of meeting head on to be provided with at ramp, by wire rope pulling scraper head 8, quick-fried rock 6 is down harrowed in the simple and easy chute 11, and the mine car 3 of directly packing into is transported.
(4), rake road rock 4 explosions between 2 base plates of knick point 9 to Chuan Mai tunnels are transported, whole small-sized ramp construction finishes.
Adopting said method is successful Application in Jiao family's gold mine many places small-sized ramp work progress, rake slag distance reaches 60m, and production efficiency is brought up to 3m/d by the 2m/d of artificial haulage rock, and efficient has improved 50%, and effectively reduce operating personnel 2～3 people, obviously improve safety condition.
