技术领域 technical field

However, because the roof of the working face falls at any time, the environment in the goaf is very complicated, especially the reference point is difficult to find, and it is still very difficult to test the displacement of the bottom plate of the working face. Some scientific workers use the drilling method for measurement. The main plan is to dig a special detection lane on the bottom plate of the working face, and then construct a drill hole upwards, install corks at the corresponding layers in the drill holes, and tie a cork on the cork. Thin iron wire, through testing the iron wire to reflect the displacement of the bottom plate of the working face. However, the measurement accuracy of this method is low, and the cork is easy to fall off, and it is very inconvenient to drill a special roadway on the floor of the working face to arrange drilling holes. In some working faces, there is even no condition for driving a detection roadway at all.

本实用新型的用于煤矿工作面底板的位移测量器,由底部固定座1、保护管2、连接绳3、弹簧支板4、弹簧5、注浆孔6、活塞7、随岩运动器8、柱桶9、传输管10、读数器11组成。底部固定座1为圆柱体,设在底部岩石12内,高0.5m,直径根据相应的钻孔13的直径确定;连接绳3为一抗拉强度较大的钢丝绳,连接绳3的下端与底部固定座1连接,上端与随岩运动器8中的活塞7相连,随岩运动器8设在待测岩层14处;连接绳3的外部装有保护管2,保护管由多节金属套管连接而成,每节套管长1.5m直径约3-4cm。每节套管上细下粗,下部的内径等于上部的外径,连接时将上部套入下部即可。保护管2一端连接底部固定座1,另一端连接弹簧支板4,弹簧支板4与弹簧5一端连接,弹簧5另一端与活塞7连接。随岩运动器8为圆筒形,高度0.5m,直径略小于钻孔的直径,内腔下部装有活塞7、弹簧5、弹簧支板4,活塞7下端与连接绳3连接,活塞7与随岩运动器8内腔密闭良好,传输管10是内软管外套金属管的双套管,一端与随岩运动器8相连,另一端与读数器11相连;传输管10引出风巷15,其端部的读数器11为透明圆筒形,刻有标准刻度;随岩运动器8与传输管10的密封腔内充满指示液,指示液有两种颜色,用两种液体颜色的分界面做为读数器的读数点。The utility model is used for the displacement measuring device of the bottom plate of the coal mine working face, which consists of a bottom fixing seat 1, a protection tube 2, a connecting rope 3, a
工作过程:在工作面未开采之前,在切眼内或其它适合的位置施工钻孔13,钻孔完成后,将底部固定座1与连接绳3连接好,然后安上第一节保护管2,放入钻孔内,卡住连接绳3,使底部固定座1及保护管2不掉下去,接着套上第二节保护管2,再放入钻孔内,如此直到保护管2安装完毕,然后将弹簧支架4、弹簧5、连接绳3、活塞7、柱桶9依次接上,将以上连接体缓慢放入钻孔内,同时接上传输管10,当整个装置安放到位,通过注浆孔5向钻孔内注水泥浆或化学浆液,将整个钻孔封住。并将传输管10从钻孔内引出,沿工作面底板铺设好,并用铁管套住加以保护,传输管10延伸至观测点,接上读数器11,注入指示液,使指示液两种颜色的分界面位于读数器11的零点位置。当工作面开采之后,工作面底板的岩层在地下水压力的作用和矿山压力的作用下会发生向上运动,当待测岩层14发生运动时,会带动随岩运动器的柱桶9也向上运动,这时活塞7由于与底部固定座1相连而静止(或运动量很小),活塞7和柱桶9就会发生相对位移,柱桶9内的指示液也要向下运动,由于随岩运动器8通过传输管10与读数器11相连通,所以读数器11内的指示液也会下降,通过读出指示液的下降值并除以面积的倍数就可以得到待测岩层14的位移量。Working process: Before the working face is mined, construct the
