Abstract
The invention provides a method for filling a resin explosive cartridge in a drilled hole of a tunnel roof anchor rod. According to the method, multiple sections of sleeves are combined into a one-piece telescopic pipe; according to the depth of the drilled hole of the roof, the telescopic pipe is stretched to a required height, the upper port of the telescopic pipe is inserted into the drilled hole firstly, and then the resin explosive cartridge is filled into the telescopic pipe through the lower port of the telescopic port; the resin explosive cartridge is slowly pushed to the deepest part of the drilled hole along the wall of the telescopic pipe by virtue of a push rod, so that the resin explosive cartridge is bonded with the wall rock formation of the drilled hole; then the push rod is pulled out from the telescopic pipe, and the telescopic pipe is drawn out from the drilled hole after being shortened; and finally the explosive cartridge is stirred after an anchor rod is inserted, so that the difficult problem that workers cannot feed the explosive cartridge into the bottom of the drilled hole timely and effectively when the interior of the roof is crushed to form a hole or the roof is lapped ahead of time can be solved; and meanwhile, when the height of a tunnel exceeds 3m, the workers have no need of utilizing tools such as a scaffold, and only need to appropriately stretch the telescopic pipe according to the height of the tunnel, the working efficiency is improved, and the risk existing when the workers fill the resin explosive cartridge in the roof anchor rod is eliminated.
Description
Technical field
The present invention relates to a kind of method of casting resin powder stick, be especially a kind ofly applicable to the back armature boring casting resin powder stick method of the more broken and head-room in back rock stratum at 3.0 more than m.
Background technology
China's coal-mine started to use suspension roof support in rock gangway in 1956, so far the history of existing more than 50 year.Bolt support technology experienced by from low-intensity, high strength to the evolution of high pre-stress, powerful supporting.China's coal-mine suspension roof support is application success in rock gangway first, and in rock gangway, widely popularize the Shotcrete Rockbolt Support Technique that to apply with " three is little " be representative.The suspension roof support sixties of 20th century starts to be applied to mining roadway.Due to heading country rock relatively soft broken, be subject to mining influence again, deformation of the surrounding rock in tunnel is large, requires high to support technology.The Anchoring Strength of Rock Bolts that China adopts in early days, rigidity are low, and support principle still belongs to passive protecting, and anchor rod supporting theory, method for designing, support material, construction equipment, monitoring instrument etc. are also immature in addition, cause BOLTING TECHNOLOGY TO COAL ROADWAY slower development.Nineteen ninety, China's State owned coal mine coal entry anchor rod support only accounts for 3% ~ 5%, and coal roadway support is mainly based on shed ding support.
In the enforcement period of the ninth five-year plan, former Ministry of Coal Industry is classified as BOLTING TECHNOLOGY TO COAL ROADWAY as emphasis problem, expands more deep, careful and comprehensive development test work.Particularly 1996-1997 China has introduced Australian bolt support technology, has carried out on-the-spot demonstration in Xingtai Mining Industry Bureau.Simultaneously through the research cooperation of scientific research institutions, universities and colleges and coal enterprise, China's BOLTING TECHNOLOGY TO COAL ROADWAY is improved a lot.High-strength deformed steel bar anchor pole also carries out lengthening or total length resin anchoring, dynamic shoring method for designing, new technology, new material, the new methods such as small-bore resin anchoring prestress anchorage cable are extensively approved, be applied to the hard situations such as tunnel, coal top, compound and breaking roof tunnel, obtain good supporting effect and technical economic benefit.
Since entering 2l century, along with fast development and the large-area applications of mining, high seam full-seam mining production technique, higher requirement is proposed to BOLTING TECHNOLOGY TO COAL ROADWAY.Mining and all-time high mining face General Requirements stope drift active workings are arranged along seat earth, and back is more broken coal seam, sometimes or even whole enzymatic method.In addition, along with increasing substantially of coal mining intensity and output, the drift section of requirement is increasing.In order to reduce Coal Loss, gob side entry driving is applied more and more wider.All these makes roadway support difficulty significantly increase.For this reason, Yanzhou, the Lushui River peace, Jincheng, Western Hills, Huainan, the Huaibei, Xin Wen, Longkou, open the mining areas such as Luan, iron processes, Xuzhou, Huating in succession carried out this mining area coal entry anchor rod support complete set technology research, test and apply.Suspension roof support to be succeeded application at hard situations such as large section roadway, coal top and whole enzymatic method, gob side entry driving, soft and broken surrounding rocks tunnels, significantly improve supporting effect of roadway, reduce support cost, for the quick propelling of coal-face, mine realizes high-yield and high-efficiency and creates good condition.
In recent years, in order to solve high-ground stress tunnel, deep, extra-large cross-section tunnel, by complicated hard situation supporting difficult problems such as strong mining influence tunnel, gob side entry retainings, China develops again high pre-stress, reinforced anchor rod and cable bolting technology, really achieve the active of anchor pole, immediate support, give full play to the support action of anchor pole.Down-hole application drastically reduce the area deformation of the surrounding rock in tunnel and destruction, and roadway support and safe condition there occurs essence and change.Meanwhile, achieve the modern Design of bolt support theory of " three high and one low " of high strength, high rigidity, high reliability and low support density, under the prerequisite ensureing supporting effect, significantly improve tunnelling speed and work efficiency.
Through years of researches and practice, up to the present, can say that China's coal-mine has defined coal entry anchor rod support complete set technology system with Chinese characteristics, suspension roof support become coal mine roadway first-selection, main support pattern safely and efficiently.But, due to when excavating tunnel, form crushed zone in roof strata, the longitudinal cranny development of top board is more abundant, cause around hole wall of being everlasting, occur cavity among a small circle when beating roof bolt hole, this makes to be difficult to it to be filled to foot of hole smoothly when casting resin powder stick; And in some tunnels, run into the situation first spreading and beat anchor pole after wire netting sometimes, workman when filling roofbolt resin explosive roll because the obstruct of wire netting is difficult to powder stick is filled to deep of holing; Moreover the vertical distance of drift section of some mine is comparatively large, and workman is when filling roofbolt powder stick, need by aids such as high foot rests, need several workman to cooperatively interact simultaneously and just can complete filling task, lessen operating efficiency like this, affect tunnel fltting speed.Above problem has all seriously run counter to the original intention that tunnel safety is efficiently constructed.
Summary of the invention
