Description
Technical field
The present invention relates to one and adopt fragmented rock body water sand migration pilot system and monitoring method.
Background technology
Recently as coal mining intensity continue to increase with mining up per limit constantly improve, overlying loose aquifer is by mining influence, the water sand mixture that sand content is higher is burst into mining face under mine, the geological disaster of even casualties of causing causing any property loss happens occasionally, bring the biggest threat to the safety in production of mine, seriously govern the development of coal industry.On April 20 nineteen ninety, colliery, porcelain kiln gulf occurs roof fall gushing water to burst sand disaster, and water yield reaches 200m3/ h, total sand amount 4000m of bursting3Above, causing a 304m long belt lane, exploiting field to be reached 2m (tunnel height 4.5m) by sandfilling thickness, ground forms cone and collapses hole (diameter 28m, deep 14m), and water level declines rapidly, and reservoir dries up.Nineteen ninety December 28 days, colliery, porcelain kiln gulf occurs again a roof fall gushing water to burst sand, water yield 50m3/ h, sand amount of bursting reaches 6000m3.On June 1st, 1996, Zhalainuoer Tie Bei repeatedly frees in ore deposit gushing water and bursts sand, due to II2aRoof work surface roof fall, the zone of fracture of formation is linked up with the first water-bearing layer, highlights water sand 1700m3.On June 22nd, 1989, Northern Huaihe River Anhui mining area hundred is apt to ore deposit 666 work surface and has been linked up the sand bottom unconsolidated formation because repeatedly caunching the strongly weathered sand-rock destroying on top board, highlights water sand 1000m3.On October 31st, 2002, there is sand accident of bursting in Yokogawa colliery, Zoucheng City 1931E work surface, 2 personnel are trapped in tunnel.Huaibei mining industry group company Taoyuan Coal Mine two on November 10th, 2002 exploiting field 1022OnWork surface (preparation face), cuts eye generation suitable for reading gushing water, sand accident of bursting, dead 4 people, injured 1 people, direct economic loss more than 130 ten thousand yuan, immediate cause: 1022OnWork surface air way is arranged in weakness, loose, broken bedrock weathering zone, cut that eye is suitable for reading repeats the canopy roof fall that collapses, caving place forms inbreak funnel, it is difficult to form caving arch, cause caving zone the most upwards to be grown until the Fourth Aquifer conducting the Fourth Aquifer, cause four aqueous, mud, sand, gravel to be burst into down-hole.Mining face under mine retention of excessive fluid is burst the generation of sand accident, not only have impact on the normal production of mine, has also threatened the life security of workman.
The steady exploitation of coal resources to be ensured, break away from gushing water to burst the serious puzzlement of sand disaster, under water body, (include surface water body and water-bearing layer) mine time, prevent from water sand from dashing forward to gush, scientific and reasonable design mining up per limit, carry out crack, mining overburden space Evolution under roof water effect, seepage flow, prominent retention of excessive fluid sand mo(u)ld are intended, it is thus achieved that water burst in face is burst sand power mechanism, is one of key issue urgently to be resolved hurrily.Due to the concealed feature of subsurface excavation engineering so that the water sand that causes of mining dashes forward the study mechanism gushed and influence factor is difficult to study by field observation, and laboratory test becomes the effective means solving this problem.By arranging the test parameterss such as different water sand mixture composition, different water pressure, different fragmented rock body combinations, quantification ground research water sand mixture migration and the multiple geological information gushed out, obtain the water pressure change curve of diverse location monitoring in different model test water sand mixed flow migration process, analyze the relation of water sand flow speed and fragmented rock body combination simultaneously, observation water sand overfall sand production rate and the variation relation of time, burst sand disaster to prevention underground gushing water and ensure that safety in production has great directive significance.
