PL100150B1 - METHOD OF PROTECTING FIELD PATHS WHEN USING STRONG SLOPES AND STEEP COAL SIDES WITH LONG CHAMBER SYSTEM - Google Patents

Description

The subject of the invention is a security method traversing field pavements with heavy use inclined and steep coal seams with a thickness of bending up to 6 meters and inclination up to 90 ° of the system meme of long chambers, shot method with long holes, for a collapse, dry filling and smooth.

From many known methods of deck exploitation steep and steep slopes for best results extraction concentration and efficiency ensure long chamber systems to enable cutting these decks from preparatory pavements long hole shooting method. Pro driving field pavements, laying long ones chambers and the order in which they are selected depend on type of exploitation - collapse, dry filling and smooth. In all these cases, the horse it is not necessary to use a suitable housing field pavements, preventing their speed destruction over the exploited chamber and po improving the stability of the ceiling in the chamber, so that in the forehead it was possible to choose freely shot coal.

So far, there is no such security method of field pavements during engine operation no sloping and steep decks that was corresponded to the current requirements of concentration, productivity and safety at work. Because it, the mines, although they have access to it significant carbon deposits in strongly sloping decks steep and steep, they give up the exploitation of these fires clades or runs it locally in a small area end.

The object of the invention is to remedy the above drawbacks and inconvenience, and to provide rhythmic and without safe operation of steeply inclined decks and steep.

This aim was achieved by means of the method of operation securing field walkways according to inventions the chair, when operating on very inclined and steep slopes my carbon decks with a system of long chambers.

The essence of the invention consists in the fact that the poem you have several divergent holes in the sides walking field markers from below and above rice intended for mining lots of coal deck.

Then a safety guard is placed in these holes sealant hews the anchors, assuming at the same time canopies between the anchors embedded in the hole located at the carbon ceilings the aforementioned field walkways. Moreover, in carbon ceiling of the upper field walkway it is also possible to drill holes parallel to the sawdust the owls of this pavement and place the anchors in them additionally securing canopies, most preferably w halfway between the anchors at the same time a carbon footprint. Before everyone by shooting long holes, it is removed in turn the roof rails of the lower field walk nika.

This way of securing field pavements 1001503 100 150 4 According to the invention, the housing is made independent of the circuit breaker taking coal on board and preventing rapid destruction of the field pavement over used chamber and improves the stability of the sides pu in the chamber so that the face can be freely select the blasted coal. Fastening canopy with anchors, density of anchors in the ceiling and sawdust yes, they are dependent on local conditions and circumstances Means sat down by mines. Anchors can be steel, wooden, plastic or mixed, wedge-shaped, spreading or glued, incl depends on local conditions and mine recognition.

The subject matter of the invention is illustrated in example the clade embodiment in the drawing in which Fig. 1 presents pavements secured with anchors longitudinal section, and Fig. 2 is a sectional view along the line A-A in Fig. 1.

In the steep deck lot intended for of exploitation, appropriate fields are separated, "which divided by field galleries 1, 2 per equivalent no stripes. carbon, the so-called chambers 3 et seq they are not operated towards the field boundary.

Running field sidewalks 1, 2, layout 3 long chambers and their order of selection, depends They are different from the type of exploitation - collapsing filling dry or liquid. Regardless of the type of explosion access, field walkways 1, 2 is secured by a method I am according to the invention. This method consists in that several divergent holes are drilled first 4, 5 in the side walls of 6 field pavements 1. 2, and na¬ steppes are placed in these holes for protection looming hews 6 bolts 7, 8. Simultaneously, room between the anchors 7 embedded in the holes 4 situated at 9-bay coal ceilings sidewalks 1, 2 are assumed roof rails 10. Moreover in the carbon 9 ceiling of the upper field walkway 1, holes 11 are drilled parallel to the sides 6 on the pavement and the anchors 12 are placed in them additionally, attaching the canopies 10 in the middle of the distance the volume between the anchors located at it carbon ceiling 9.

Before each shooting with 13 long holes, 14 roof rails 10 are removed in the following Zabrze lower field sidewalk 2. Blown off material rolls onto lower halfway 2 and over the power of a suitable loader, combine harvester the sliding chute 16 is loaded on the holding conveyor 17. Pick point the shot material 15 is sufficiently protected baked top field walkway 1 with reinforcing anchors 7, 8 on both sidewalks 1, 2. After selecting the spoil 15, the shot is shot on Stepny Zabór 18 and will load coal.

Operation of chamber 3 prepared for bleed-out wounds with field walkways 1, 2 secured method according to the invention consists only in shooting and loading the appropriate zabiorów in¬ gla. Labor-intensive execution is eliminated here housing, occupying an average of 70% of the time su. As a result, exploitation with the system of long horses a sea with pavements secured by the method of the debt of the invention increases the concentration several times extraction rates and efficiency in relation to known operating systems in steep decks.

Claims (2)

Patent claims 1. Method of securing field sidewalks: when exploiting strongly inclined and steep coal seams with a system of long chambers, worked by the method of shooting with long holes, characterized by first drilling several divergent holes (4, 5) in the sides (6) of the pavements field (1, 2) defining the bottom and top parts of the coal deck intended for mining, and then places in these holes securing the sides (6) of the bolts (7, 8), at the same time installing the canopies (10) between the bolts (7) embedded in the openings (4) located at the coal ceilings (9) of the above-mentioned field sidewalks (1, 2), with the long holes (13) being removed in successive flanges (14, 18) of the lower roofs (10) the field walkway (2). 2. The method according to claim A method according to claim 1, characterized in that holes (11) are drilled in the carbon roof (9) of the upper half-way walkway (1) parallel to the side walls (6) of the pavement, and anchors (12) are placed in them to additionally fix the canopy (10), most preferably at half the distance between the anchors (7> located on this carbon ceiling (9). 15 20 25 30 35 40 100 150 9 1 S_.
