我国水力采煤技术经过４３年的实践，已发展到比较成熟的阶段。但与其它国家相比，还存在一些差距。现科研单位与厂矿共同研制的一批科研成果，如ＳＧＷＳ—７５型煤水刮板输送机；ＹＳＸ型液控及ＳＱ型手动水枪；以斜管沉淀仓为主装置的井下煤泥水澄清和循环复用工艺及设备；专为加快水采矿井巷道掘进而研制的ＥＭＳ—７５型以及水旱采通用的ＥＢＺ—７５型半煤岩掘进机；ＤＤＭ３６０型煤水泵、ＤＮＭ３００—８０型煤泥泵；为加强水采生产管理和监测的微电脑超声波流量计、核密度计等均还未能广泛应用于生产。故要进一步提高水采矿井单产、工效，非常有必要依靠科技进步和加速科技成果转化，并选用先进科技监测设备，完善水采工艺，以促进水采矿井生产向集中、高产高效方面发展
After 43 years of practice, China’s hydraulic coal mining technology has developed to a relatively mature stage. However, compared with other countries, there are still some gaps. Research institutes and factories and mines are now jointly developed a number of scientific research achievements, such as the SGWS-75-type coal-water scraper conveyor; YSX-type liquid control and SQ-type manual water gun; inclined tube sedimentation tank-based coal slurry clarification and circulation Reuse technology and equipment; designed to speed up waterway tunneling developed by EMS-75-type and water and drought mining universal EBZ-75 semi-coal roadheader; DDM360-type coal pump, DNM300-80 slime pump; To enhance water production management and monitoring of micro-computer ultrasonic flowmeters, nuclear density meters have not yet been widely used in production. Therefore, it is necessary to further improve the yield and efficiency of water mining mines. It is very necessary to rely on scientific and technological progress and speed up the transformation of scientific and technological achievements. We also select advanced scientific and technological monitoring equipment and improve the water mining technology so as to promote the development of water mining mines to focus on high yield and high efficiency
