Repeat mining thick coal seam floor rock mass damage when the depth of [J]. Coal Geology & Exploration, l995, 23 (4): 4449. About Ng Man (1961 a), male, Anhui Shucheng, PhD, Professor, Bo ten tutor, China Coal Mine Geological Society of Professional Committee of the Secretary-General, director of the Geological Society of Anhui Province, Anhui Province, Institute of Flood Control of coal Professional Committee . Engaged in coal mining engineering geology and geological hazards and other aspects of teaching and research work. Has assumed the Provincial Natural Science Foundation of Excellent Youth Foundation of the Ministry of Coal and other portrait subjects more than l0, enterprises and more than 40 cooperation projects; by the Anhui Science and Technology Progress Award 3. More than 6O published articles, monographs published 3. Ukraine About Ukraine drilling special drilling technology company in Ukraine and Russia, 1950-2000 a total of 462 drilling shaft, the cumulative total length of 180km, drilling diameter of 1 ~ 5m. In Donetsk and Kuznetsk area, for ventilation, security, export and used for transporting personnel, materials, shaft, drilling diameter of 3 ~ 5m; for laying pipes and cables shaft, drilling diameter of 1 ~ 2m. Le Siji in the Krasnoyarsk Territory as a water surface mine that ETHNO Ostrovsky shaft wells, drilling diameter of 5m. Vinod City in the Moscow Region Brott acceleration device for placing the instrument shaft, drilling diameter of 5.6m. Allah states in the Romano Marco Fu Han-day mining for diamond mining shaft, drilling diameter of 4m. Currently, the Ukrainian special drilling rig used by the company in two models. One is the German company's L-WIRTH drilling rig, a I-4, B a 35, I a 35K, L a 35M, I and L-35MPK6 a 35MP models. Such drilling rig derrick with 4 legs and columns, high 15 ~ 28m, the bottom mast cross dimension 2.5 ~ 7.4m. Drilling diameter to fit 2.6 ~ 4.0m, can be a drilling depth of 7001000m of L 35, L-35K drilling rig, for example, its main technical parameters are: capacity building 3500kN, dial torque 420kN ・ m, 6 speed dial 17r/min; drill pipe diameter 356/330mm, drill pipe length 4.5/9.0m, drill pipe weight 1460 ~ 1850N / m; compressor capacity of 23m. / Rain, with 2 units, compressed air pressure of 13bar; equipment power 4 × 200kW, power supply voltage of 380V; ground equipment, the total mass of 200t. Installation time is about 20d, the operator 6, month footage of up to 120 - 140m. The other is made of the RTP-type turbine Ukraine drilling machine, type more, there are a RTP 1020,[link widoczny dla zalogowanych], RTP RTP a 4000 a 2600,[link widoczny dla zalogowanych], and three; with steel headframe,[link widoczny dla zalogowanych], high 22 ~ 42m, suitable for drilling diameter of 0.4 ~ 5 .0 m, the drilling depth of 300 ~ 1000m. Turbine drilling machine ground equipment technical characteristics: Lifting capacity 500 ~ 2000kN; with Y8-6-type mud pump 2 to 4, the pump pressure 90bar, pump efficiency 100n200I / s, total power 1500 ~ 25O0kw; supply voltage 380 and 6000V; equipment the total mass of 100 ~ 300t. Downhole Equipment Technical characteristics: the number of X diameter of the turbine drill 2X2404X240, turbine number × diameter 2 × 490 ~ 3 × 620 +1 × 750, turbo-speed 600 ~ 800r/rain, fluid consumption 1O0 ~ 200I / s; the whole unit speed 2 ~ 15r/rain; be equipped with pumps 2 to 4; equipment weight 132 ~ 590kN. Used drill pipe diameter 168.3mm, the drill pipe wall thickness of 9mm,[link widoczny dla zalogowanych], the drill pipe length of 6.8 ~ 11.5m,[link widoczny dla zalogowanych], weight per m drill 35o ~ 390N. Such drilling installation to be 30 ~ 6od, 4 to 5 per class operator who, on footage of up to 3O ~ 300m. Drilling process, using a 4 HM Inclinometer Inspection drilling skewed to meet the construction requirements, rate of vertical borehole deviation does not exceed 1 ‰. When the flood depth is not only about 30m, the use of drilling sink sinking, drilling the concrete side of construction is sinking steel tube side wall. Steel tube wall with the bottom edge of the foot cone hob, sink with drilling, and gradually remove the rock wall steel tube, steel tube outer wall mud protection. After sinking to the design depth of drilling, the steel tube as the caisson wall to wall. (Yong-Cheng Zhang)
