Inclined layered solid-filling mining method in ultrathick coal layer

An inclined layered solid-filling mining method in an ultrathick coal layer is applicable to exploitation in a “three-unders” ultrathick coal layer. In this method, the number of inclined layers is determined based on a principle of layered thickness from 2.5 m to 4.5 m, and a layered-exploitation downward-filling exploitation order is adopted. Tunnels and equipment are arranged according to a conventional solid-filling mining method. A cyclic order of mining, layout of metal meshes ( 14 ) and bamboo fences ( 24 ), and filling is adopted, so as to accomplish filling and exploitation of a first mining face and a first layer ( 21 ). Meanwhile, 4 months after the working face of this layer is finished, at a corresponding position in a second layer ( 22 ), under the cover of an artificial ceiling formed by the first layer ( 21 ), exploitation is performed by using the same filling mining method; such a cycle is repeated, and exploitation in a current layer is performed under the cover of an artificial ceiling fabricated by an upper layer, until the entire ultrathick coal layer is finished. When this method is adopted to exploit “three-unders” ultrathick coal layer resources, strata movement and earth surface subsidence may be effectively controlled; the method has a high extraction rate, high production efficiency, and low cost.

Inclined layered solid-filling mining method in ultrathick coal layer

An inclined layered solid-filling mining method in an ultrathick coal layer is applicable to exploitation in a "three-unders" ultrathick coal layer. In this method, the number of inclined layers is determined based on a principle of layered thickness from 2.5 m to 4.5 m, and a layered-exploitation downward-filling exploitation order is adopted. Tunnels and equipment are arranged according to a conventional solid-filling mining method. A cyclic order of mining, layout of metal meshes (14) and bamboo fences (24), and filling is adopted, so as to accomplish filling and exploitation of a first mining face and a first layer (21). Meanwhile, 4 months after the working face of this layer is finished, at a corresponding position in a second layer (22), under the cover of an artificial ceiling formed by the first layer (21), exploitation is performed by using the same filling mining method; such a cycle is repeated, and exploitation in a current layer is performed under the cover of an artificial ceiling fabricated by an upper layer, until the entire ultrathick coal layer is finished. When this method is adopted to exploit "three-unders" ultrathick coal layer resources, strata movement and earth surface subsidence may be effectively controlled; the method has a high extraction rate, high production efficiency, and low cost.

Longwall frame

Beim Abbau mit Blasversatz erfolgt bei den bekannten Strebausbaugestellen die Demontage des Blasrohrstrangs über fensterartige Öffnungen in den klappbar gestalteten Versatzwänden. Die Klappbarkeit der Versatzwand verhindert aber einen Einsatz in niedrigen Flözmächtigkeiten, weil die Bergleute dann über die Öffnungen nicht mehr an die Kupplungsstellen heran können. Zum Schutz des Strebraums sind dann andere Maßnahmen in Form von z.B. unabhängig ver lagerbaren Blaswänden zu treffen. Durch die Erfindung wird jetzt der Gestellklappe (5) und der Gestellkurve (4) je ein Wandabschnitt (10, 11) zugeordnet, die vertikal zueinander verlagerbar sind. Jeder Wandabschnitt (10, 11) ist außerdem in Streblängsrichtung teleskopierbar. Durch Verlagerung der Teleskopteile (14, 15) können auf diese Weise Montagemassen (36) geschaffen werden, über welche die Kupplungsstellen (37) des Blasrohrstrangs (32) ohne Schwierigkeiten zugänglich werden. When dismantling with blow offset, the known longwall construction frames are used to dismantle the blowpipe string via window-like openings in the foldable offset walls. The fact that the backfill wall can be folded up prevents it from being used in low seams, because the miners can then no longer get to the coupling points through the openings. To protect the face, other measures must then be taken in the form of, for example, independently relocatable blow walls. As a result of the invention, the frame flap (5) and the frame curve (4) are each assigned a wall section (10, 11) which can be displaced vertically with respect to one another. Each wall section (10, 11) can also be telescoped in the longitudinal direction of the face. By moving the telescopic parts (14, 15), assembly masses (36) can be created in this way, via which the coupling points (37) of the blowpipe line (32) can be accessed without difficulty.

本发明公开了一种隔舱式充填开采方法及设备，所述方法包括：在液压支架后方设置浇筑模架和输料管道，当工作面向前推进时，将适当比例的混凝土、速凝剂以及破碎的矸石通过输料管道输入浇筑模架，浇筑成型后形成对顶板的支撑，随着工作面的推进，进行连续浇筑，形成沿顶板支撑墙，根据实际情况选取适当位置在相邻的支撑墙之间浇筑封堵墙，形成隔舱，在对顶板形成支撑，防止出现大范围的顶板垮落，防止破坏上部含水层、隔水层，实现了高效充填开采的同时，对采空区的空间进行了分隔，避免了大范围的瓦斯聚集和矿井水沟通，降低了工作面的通风量需求，从多个方面提升了井下安全生产水平。

一种放顶式矸石充填液压支架及填充方法

本发明提供了一种放顶式矸石充填液压支架及填充方法，由顶梁、掩护梁、底座和连接顶梁与底座之间的四根立柱、反四连杆组成，掩护梁与反四连杆底座之间通过支撑油缸连接，在掩护梁下设有与底座连接的骑跨式平台，平台上装配底卸式漏矸刮板，矸石通过漏矸孔充填采空区；对于放顶煤充填工作面，提供了割煤、移架、推前溜、充矸、放煤、拉后溜的填充方法。本发明充填液压支架工作阻力大，掩护梁有效围挡架尾冒落岩块或煤块，为骑跨式平台及充填提供安全围护空间，可实现不充或少充；采用骑跨式平台承托底卸漏矸刮板，可增大工作面宽度及下部充填空间，可采充平行作业，实现了同一综采充填工作面既能不充、又能少充、更能快充的目的。

一种固废胶结密实充填开采液压支架

本发明公开了一种固废胶结密实充填开采液压支架，包括架体部分、固体充填骨料输送部分、复合充填部分和充填反馈部分；复合充填部分包括螺旋推压装置和胶结浆液施加装置，螺旋推压装置设置在底座上，包括滑座、螺旋推压组件和充填隔离立板，胶结浆液施加装置包括胶结浆液输送管路和充填区注浆管；充填反馈部分包括光纤应力传感器和液位传感器。本发明先通过螺旋推压装置持续向采空区内充填并挤压固体充填骨料以提高固体充填骨料的充填密实度，再通过胶结浆液施加装置向已初步挤压密实的固体充填骨料充填体施加胶结浆液充填固体充填骨料颗粒之间的空隙，可获得稳定高密实度充填体，能够在控制充填体初期变形的前提下有效控制地表的长期缓慢变形。
