Embodiment Construction

[0029] The construction method of an all-coal extra-large cross-section crossing chamber under the condition of uninterrupted transportation of the main roadway according to the present invention includes the construction of the lap joint chamber construction of the panel tape machine head, the construction of the lap joint chamber construction of the working face belt lane, and the construction of the working face belt Lane maintenance, the specific construction steps are (such as figure 1 shown):

[0030] (1) The head of the panel tape is lapped to the arch of the chamber,

[0031] (2) Maintenance of the working face belt lane, auxiliary facilities and cable protection,

[0032] (3) The construction of the arch portion of the chamber where the belt lane is lapped at the working face,

[0033] (4) Lap-joint chambers of belt machine heads in the penetrating panel and lap-joint chambers of belt lanes on the working face,

[0034] (5) The construction of the overlapping of th...

Abstract

The invention discloses a method for constructing cross-over chambers with a full-coal outsize cross section under a host lane ceaseless transportation condition. The method comprises the steps of: construction for lap joint between a panel adhesive tape machine head and a camber, construction for lap joint between a working face belt lane and a chamber and maintenance for the working face belt lane, and specifically comprises the steps of: (1) performing the lap joint construction on the panel adhesive tape machine head and the arc part of the chamber, (2) maintaining the working face belt lane and protecting auxiliary facilities and cables, (3) performing lap joint construction between the working face belt lane and the arc part of the chamber, (4) penetrating through the chamber in lap joint with the panel adhesive tape machine head and the chamber in lap joint with the working face belt lane, (5) performing wall part construction on the chamber in lap joint with the panel adhesive tape machine head and performing large brushing construction on the chamber in lap joint with the working face belt lane, (6) performing arch building on the chamber in lap joint with the panel adhesive tape machine head and the chamber in lap joint with the working face belt lane, and (7) performing arch building on a cross-over point between the chamber in lap joint with the panel adhesive tape machine head and the chamber in lap joint with the working face belt lane. According to the invention, the transportation of the working face belt lane is not influenced during construction, and the difficult in performing chamber construction under a full-coal-seal geological condition is eliminated.

Description

technical field [0001] The invention relates to a construction method for an underground chamber in a coal mine, in particular to a construction method for an all-coal extra-large cross-section cross chamber under the condition of uninterrupted transportation in a main roadway. Background technique [0002] In coal mine production, it is often necessary to arrange new panels near existing panels, and the working faces of adjacent panels are produced simultaneously. In order to facilitate production, transportation or avoid accidents, sometimes it is necessary to overlap the belt of the new panel with the belt of the working face of another panel that undertakes the transportation task to form a panel transportation system, so it is necessary to construct a crossing chamber ( The panel overlapping chamber and the working face overlapping chamber) connect the panel belt alley with the working face belt alley. [0003] During coal mining, if the thickness of the coal se...
