Hydraulic Support for Complex and Difficult to Mine Coal Seams

Hydraulic Support for Complex and Difficult to Mine Coal Seams  PRODUCTION INTRODUCTION  Hydraulic supports for complex and difficult to mine coal seams are the company's flagship products with independent intellectual property rights. Equipment selection, matching, and development can be carried out based on specific geological conditions, and coal mining services or guidance services can be provided.The hydraulic support for extremely thin coal seams is suitable for mechanized or automated mining of coal seams with a height of 0.6 ~ 0.8m. On the basis of ensuring the reliability and stability of the support, it provides greater operating and maintenance space. Equipped with anti-overturning and anti-slip devices, it can adapt to the mining of large angle coal seams.The steeply inclined hydraulic support is equipped with a unique structural design, complete anti-overturning and anti-slip devices, and a "three in one" protective device, which can adapt to coal seam dip angle up to 85°; The hydraulic support with a large inclination angle is equipped with "longitudinal" stabilizing mechanisms such as anti-drift and anti-backpull, which can adapt to double dip coal seams with a strike inclination angle of up to 25°. By optimizing the structural parameters and control methods of the support, it can adapt to the "three soft" coal seam conditions.The filling support meets the needs of mining in the "three below" coal seam and can adapt to various filling processes such as gangue, paste, and (ultra) high water.      TECHNICAL SPECIFICATIONS AND PARAMETERS  Hydraulic Support for Complex and Difficult to Mine Coal SeamsExtremely Thin Coal SeamZZ3400/4. 5/7.5Ddip angle≤45°Electric ControlZZ4000/05/09Ddip angle≤45°ZZ4400/5. 5/10.5Ddip angle≤45°ZZ4000/06/12Ddip angle≤45°Pilot/ Manual ControlZZ4000/6. 5/13Ddip angle≤45°Steeply Inclined Coal SeamZY2400/8. 5/15. 5JDdip angle≤85°Electric ControlZY2400/09/19JDZY3600/12/28JDZY5000/15. 5/38JDHigh Dip Coal SeamZY2800/12/26QWorking face inclination angle≤45°Strike dip angle≤25°Manual, Pilot, Electronic ControlZY3600/12/28QZY2400/11/28QZY4000/15/34QZY4800/14/32QZT5000/20/40ZY3000/14/32QSZY4800/14/28QSZY5600/15/36QSZY6600/22/45QZY6800/18/38QZY7600/22/48QZQ14000/28/45ZQ20000/17/27ZQ20000/21/37Large Angle Caving CoalZY3000/16/25Qdip angle≤45°Manual, Pilot, Electronic ControlZF3800/16/26QZF4800/16/32QZF5200/17/35QZF5600/17/28Q ZF6800/17/35Q  Filling BracketZC3200/12/26Bangshi FillingManual, Pilot, Electronic ControlZC4400/16/32ZC5600/20/38ZC7000/20/40ZC9500/18/38ZC3000/09/20Paste FillingZC5000/18/35ZC6400/16/30High Water FillingZC10000/20/40   VARIOUS HYDRAULIC SUPPORTS SUPPLYWe can supply various kinds of hydraulic supports including shield hydraulic support, support shield hydraulic support, top coal caving support, mesh laying support, lightweight support, and support for miscellaneous mining coal seams such as extremely thin coal seams, large dip coal seams and steep dip coal seams, to meet the requirements of different rock relationships and mining processes. At present, hydraulic supports have formed various series of products with working resistance ranging from 1100KN to 26000KN and support height ranging from 450mm to 8800mm.    HYDRAULIC SUPPORT WORKSHOP   COMPANY INTRODUCTIONEstablished in 1955, Shandong Mining Machinery Group Co., Ltd.
