Description

Изобретение относитс  к области угольной промышленности и может -быть использовано при разработке пологопадающих угольных пластов длинными очистными забо ми, движущи .мис  как по простиранию, так и по восстанию (падению) пласта.The invention relates to the field of the coal industry and can be used in the development of gently dipping coal seams with long cleansing holes, moving both along the strike and along the rise (dip) of the reservoir.

Известен способ поддержани  подготовительных выработок, заключающийс  в том, что после отработки запасов, расположенных по юдну сторону выработки, стойку крепи, прилегающую к выработанному пространству, вслед за иодвиганием очистного забо  опускают на величину ожидаемой конвергенции (если выработка крепитс  металлическими податливыми стойками) или замен ют (укорачивают ) на меньшую по длине (если выработка крепитс  дерев нными стойками), при этом конец верхн ка, прилегающий к отработанной стороне, опускают на укороченную стойку. После отработки запасов, расположенных по другую сторону выработки, вслед за подвиганием очистного забо  стойку крепи, примыкающую к выработанному пространству , -вместе с -стано,вленным на ней верхн ком также опускают.There is a method of maintaining preparatory workings, which, after working off the reserves located on one side of the mine, a support bar adjacent to the developed space is lowered after the iodvigence of the refining slab by the amount of expected convergence (if the mine is attached by metal pliable racks) or replaced (shortened) for a shorter length (if the production is fixed with wooden poles), while the end of the top, adjacent to the waste side, is lowered onto the shortened stand. After working off the reserves located on the other side of the mine, after the advancement of the clearing floor, the lining adjoining the worked out space, together with the steel, the upper one placed on it is also lowered.

Недостатком известного способа  вл етс  невозможность увеличени  сечени  выработок без дополнительных затрат на их проведение и перекренление.The disadvantage of this method is the impossibility of increasing the cross-section of the workings without the additional costs of their holding and re-cutting.

Цель изобретени  - устранение указанных недостатков. Это достигаетс  тем, что вслед за подвиганием очистного забо  извлекают стойку крепи, примыкающую к выработанному пространству, и опускают конец верхн ка, опирающийс  на эту стойку, до уровн  почвЫ выработки, а перед проходом очистного забол с другой стороны выработки производ т ее расширение, поднимают конец верхн ка, опирающийс  на почву выработки, и подвод т под него ранее извлеченную стойку.The purpose of the invention is to eliminate these disadvantages. This is achieved by following the advancement of the clearing intake, the support of the support adjacent to the developed space is removed, and the end of the upper support resting on this stand is lowered to the level of the working soil, and before the passage of the cleaning cleaning the other side of the working makes its expansion, raise the end of the top, resting on the soil of the mine, and the previously removed rack is brought under it.

На фиг. 1 показана схема .подготовки и отработки участка шахтного пол ; на фиг. 2 - выработка в проходке, поперечное сечение; на фиг. 3 - выработка пос.те прохода очистного забо  с одной стороны, поперечное сечение; на фиг. 4 - выработка перед проходом очистного забо  с другой стороны, поперечное сечение.FIG. 1 shows the scheme of preparation and mining of the mine floor; in fig. 2 - development in the penetration, cross section; in fig. 3 - development of the settlement of the passage of the clearing slab on one side, cross section; in fig. 4 - generation before the passage of the clearing slab on the other hand, the cross-section.

Предлагаемый способ заключаетс  в следующем .The proposed method is as follows.

При подготовке лавы 1 подготовительную выработку, используемую в дальнейшем в качестве откаточного штрека, креп т металлической шарнирно-податливой крепью, состо щей из верхн ка 2, стационарной стойки 3, установленной в месте шарнира крепи, стойки-верхн ка 4, переносной стойки 5, соединительной планки 6 и металлической сетки 7, настилаемой, как правило, на верхн к 2.In the preparation of the lava 1, the preparatory development used further as a haulage drift is fastened with a metal hinged-flexible support consisting of the top 2, the fixed stand 3 installed in the place of the hinge support, the stand-top 4, the portable stand 5, connecting strap 6 and metal mesh 7, laid, as a rule, on the top to 2.
