综采面前移支架支护顶板的速度是确定工作面支护质量的因素之一。采煤机截割速度比实际支护顶板的速度要快,因此,必须周期性停机,以便及时移架使顶板暴露面积不致过大,因而这就导致减少工作面的产量任务。 工作面支护速度取决于一系列因素,其中主要的是开采地质条件,机组结构和工艺之间的相互关系,泵站和支架液压系统特性,以及操作控制的自动化程度。 在库兹巴斯对使用1кMT型机组(阿巴谢夫斯卡娅矿)、2кMT型机组(基洛夫等矿)、 4 окп-70型机组(巴伊达耶夫斯卡娅矿)、 4 окп-70Б机组(新库斯涅茨卡娅矿)、1 окп-70E机组(十一月七日矿)和2 окп-70Б机组(泽良诺夫斯卡娅矿和沃尔柯夫矿)等开采中厚煤层的综采工作面,和用2 Yкп和кM-142型机组(拉斯巴德斯卡娅矿)和 Yкп-5型机组(列宁矿)开采厚煤层(达5m)的综采工作面,以及手动操作和自动控制的用кM-138型和кM-138д型机组
The speed of fully mechanized coal mining support moving forward to support the roof is one of the factors to determine the support quality of working face. Shearer cutting speed faster than the actual support of the roof, it must be shut down periodically, so that the timely displacement of the roof so that the exposed area will not be too large, which led to the reduction of face production tasks. The speed of face support depends on a number of factors, most notably the geological conditions of the mining, the interplay between the unit structure and process, the hydraulic system characteristics of the pump station and stand, and the degree of automation of operation control. In Kuzbass on the use of 1 кMT unit (Abaschevskaya mine), 2 кMT unit (Kirov et al), 4 окп-70 unit (Baedayevskaya mine), 4 окп-70Б unit (Neusyunskaya mine), 1 окп-70E unit (November 7 mine) and 2 окп-70Б unit (Zelenovskaya mine and Volkov mine ) And other thick coal seams, and thick coal seams (up to 5 m) with 2 Yкп and кM-142 units (Rasbardskaya Mine) and Yкп-5 units (Lenin Mine) Full-mechanized mining face, as well as manually operated and automatic control with кM-138 and кM-138д-type unit
