Description

The invention relates to mining, in particular, to the means of mechanization of backfilling operations during the immense excavation of thin gentle and inclined seams with coal scraping-rigs.

The purpose of the invention is to increase the efficiency of the construction of rubble strips with a minimum consumption of backfill material.

Fig. 1 shows a technological scheme of the excavation, a plan view; figure 2 - laying device, view in plan; on fig.Z - section aa in figure 2; figure 4 - section bb in figure 2.

The clamping device for a scraper consists of two side 1 and 2 and top 3 walls rigidly connected to each other, a rear flap 4 and a movable ploughshare 5 pivotally mounted between the side walls 1 and 2, stoppers 6 and 7 of the rear flap 4 and plowshare 5, an additional damper 8 that biases rock to the scraper earring randomly outside the stowing device, and through the bow mounted on sidewall 1, additional sidewall 9 hinged to sidewall 2, the front part th stands for wall 2 in the direction of delivery of backfill material with the ability to adjust its inclination relative to the sole within the angle of repose of the backing material using an adjusting mechanism 10, made, for example, in the form of a screw (wedge, etc.), eyes 11 and bolts 12 for connecting a stowing device with a scraper 13.

For greater rigidity of the stowing device, the upper hinge joints of the rear flap 4 and the movable plowshare 5, having an arcuate shape, as well as the rotation stop 7, are made in the form of solid axes rigidly connecting the side walls 1 and 2.

The stacker for scraper plow works as follows.

After the carbon is excavated by a scraper angle into the step of laying out the bare strip to it on one of the adjacent faces of the workings, the filling device is bolted 12, which is filled with layering material and delivered with a scraper angle

Voices, for example, to the roadway. The installation control panel shows the location of the scraperostrig in the face. Then, the reversing motion of the drive, move the scraperostrag with the filling device to the initial position for loading with the backfill material, after loading the scraperostrug is again moved to the place where the rubble strip is laid out. In this case, the filling device, approaching the portion of the filling material left on the knife, with its movable plowshare 5, begins to scrape this material and transfer it under the roof of the reservoir to the additional side wall limiting movement of the filling material into the developed space 9. Since the device is made in the form of trapezoidal a box extending in its front part (i.e. distances a and b are longer than distance c and d), it freely finds the backfilling material left earlier and pressovyva, sealing it in a ploughshare butovoj strip which perebuchivaet material footwall under roofs. Additional wall 9 limits the penetration of the filling material into the developed space and is set at an angle of repose of the filling material (48-55 °) using the mechanism 10, thus contributing to a more efficient pressing of the filling material to the roof of the reservoir and its more efficient use.

The process of laying the rubble line continues in the same way until the rubble line is laid along the entire length of the bottom. Then the filling device is removed from the scraperpost and the coal is excavated at the next step of the rubble strip, then the stowing device is again attached to the scraperostrug and the subsequent rubble strip is laid out in the same way, etc.

The length (D) of the leading part of the additional side wall 9, depending on the category of filling material, is assumed such that the backing material pressed by the plowshare does not spill out of this wall. Usually its length does not exceed 1.2-1.5 width of the stowing device in the front part, i.e. D 1.2-1.56.

MORTGAGE DEVICE FOR SCRAPER STRIP, including a removable hollow trapezoidal box, consisting of interconnected side, top and rear walls, and a movable share mounted obliquely relative to the sole at an acute angle to the side wall from the side opposite to the scraping side, characterized in that, for the purpose of increase the efficiency of the construction of rubble strips with a minimum consumption of filling material, the box is equipped with an additional side wall with an adjustment mechanism mounted on the side a positive scraper circle, the front part of which protrudes beyond the main wall in the direction of delivery of the backfill material pivotally connected to the upper wall and the additional damper, and the movable share is made in an arcuate shape, while the additional side wall is mounted with the possibility of adjusting its inclination relative to the sole within the natural angle slope of the filling material, and an additional shutter by means of a hinge is mounted on the side wall _β from the side of the scraping side.
