Description
Technical field
The utility model belongs to the coal-bed gas exploitation equipment technical field, particularly a kind of mining water power working rig of waterpower pore-forming, thin hole, reaming, slot and the pressure break etc. for reaching the ground gas drainage holes under coal mine.
Background technology
The highly gassy mine that China exists is more, and has the advantages that coal seam gas-bearing capacity is high, pressure is large, gas permeability is poor and the extraction difficulty is large.At present, the average mining depth of China's State owned coal mine mine is approximately 420 meters.Along with the further increasing of the pit mining degree of depth, geostatic stress and gas pressure also increase thereupon, and the gas pumping difficulty also further increases.By experimental study for many years, China has also formed underground gas borehole pumping method and the technique of the suitable China's coal-mine characteristics of cover gradually.The effect of down-hole drilling mash gas extraction is subject to bore diameter size, boring length and the boring impact of coal mass relief scope on every side, adopt conventional mechanical drilling machine construction large diameter borehole to exist that the hole that collapses is serious, deslagging is difficult, become the short and rig load of hole length to be the technical problems such as multiple increase how much, from technology with all there is economically sizable difficulty.Therefore, seeking a technological approaches that enlarges bore diameter, increase boring length and raising boring unload effects scope is necessary.
Simultaneously, along with the increase geostatic stress of mining depth increases gradually, boring is because the geostatic stress effect is easily collapsed, stopped up, and Acceptable life is not long, but not technology and the equipment of boring reparation at present can't be repaired the boring of collapsing, stopping up.
Along with developing rapidly of water jet theory and application technology, both at home and abroad the research of high-pressure water jet boring technology is also quite paid attention to, and dropped into a large amount of human and material resources theory and experimental study have been carried out in high-pressure water jet boring, some can creep into than the water jet rig of hard formation or water jet Aided Machine rig and succeed in developing, and have obtained increasing approval in all kinds of engineerings are used.
Aspect mash gas pumping drilling, reaming, low for projecting coal bed gas permeability, as to take out in advance weak effect characteristics, behind construction finishing drilling hole, adopt bore hole enlarging technology with high water jet to carry out reaming, namely utilize can spray high-pressure water jet, again can autorotation the reaming ejector coal body around boring is rotated cutting, move simultaneously the reaming that forms whole boring along the borehole axial direction by high pressure reaming drilling rod.After bore diameter enlarges, can increase the exposed area in coal seam, increase the relief range of boring, strengthen the radius of influence of boring, increase the hole pumping and mining gas amount, improve the extracting result of boring.Therefore; carry out the research of high-pressure water jet coal seam drilling hole counter-boring techniques and equipment, to increasing the extraction amount of coal mine gas, reduce the methane content in the colliery; reduce gas accident and occur, improve Safety of Coal Mine Production level and atmospheric environment protection aspect and be of great immediate significance.
