可摘挂抱索器架空人车远程集控设计与应用

Design and Application of Remote Centralized Control for Overhead Pedestrian Vehicles with Detachable Hanging Grips

小康煤矿位于康平煤田的东北部,隶属康平县东关镇。矿井自投产以来,截止2021年未已先后在北一、西一、南一、南二采区及西三采区共回采了33个工作面。其中,有25个工作面采用的综合机械化一次采全高放顶煤开采方法,煤层最大采出厚度达14.3m(含2煤)。大范围地下煤层开采产生了严重的地表沉陷,雨季沉陷区大面积积水。尤其是在采用综放开采的区域,地表最大下沉达4.5~6.5m,部分塌陷坑常年积水。目前西三采区是2019年经过辽宁省自然资源厅依法由大平煤矿采区边界划归到小康开采边界。w3轨道运输大巷,巷道断面宽4.2米,高3.2米,是为我矿整个w3采区服务,为主要人行通道和轨道运输巷道,共设计5个采煤工作面。w3轨道运输大巷安装了可摘挂抱索器架空人车,运行长度1700米,最大坡度9度,预计使用20年,在交接班期间运送人员,巷道同时安装了120无极绳连续牵引车一套,与架空人车相互闭锁,停运期间兼运输物料,分时段工作。目前使用中,架空人车司机1名,机头机尾各1人负责控制可摘挂乘人器,为了实现远程集控功能,首先得解决乘人座椅控制问题,即在乘降区可操控能自动挂钩与自动脱离,然后启停架空人车由地面运转队集控室远方操作,实现集控可减现场操作人员3名。

Xiaokang Coal Mine is located in the northeast of Kangping Coalfield,which belongs to Dongguan Town,Kangping County.Since the mine was put into operation,as of 2021,a total of 33 working faces have been mined in the North 1,West 1,South 1,South 2 and West 3 mining areas.Among them,25 working faces adopt a comprehensive mechanized full height caving mining method,with a maximum coal seam thickness of 14.3m(including 2 coal seams).The large-scale underground coal seam mining has resulted in severe surface subsidence,and a large area of water accumulation in the subsidence area during the rainy season.Especially in areas using fully mechanized top coal caving mining,the maximum surface subsidence reaches 4.5-6.5m,and some collapse pits accumulate water year-round.At present,the West 3 mining area was legally transferred from the Daping Coal Mine mining area boundary to the Xiaokang Mining Area boundary by the Liaoning Provincial Department of Natural Resources in 2019.The w3 rail transportation roadway has a section width of 4.2 meters and a height of 3.2 meters.It serves the entire w3 mining area of our mine and is designed as the main pedestrian passage and rail transportation roadway,with a total of 5 coal mining working faces.The w3 rail transportation main lane is equipped with a detachable hanging and holding rope overhead pedestrian car,with a running length of 1700 meters and a maximum slope of 9 degrees,which is expected to be used for 20 years.During the handover period,personnel are transported.At the same time,a set of 120 endless rope continuous tractor is installed in the lane,which is interlocked with the overhead pedestrian car.During the shutdown period,materials are also transported and work is divided into different periods.At present,there is one overhead passenger car driver,and one person at the head and tail of the machine is responsible for controlling the detachable passenger car.In order to achieve remote centralized control function,it is necessary to first solve the problem of passenger seat control,which can be controlled to automatically hook and detach in the boarding and landing area.The start and stop of the overhead passenger car are remotely operated by the ground operation team's centralized control room,achieving centralized control and reducing the number of on-site operators by three.
