摘要/Abstract

摘要： 针对公乌素煤矿011604综放长工作面拐点前后不等长、两巷拐点不同心的不利条件，采用机尾过拐点后加支架，机头虚心分段调斜的方法转采，并对于调斜转采中出现的挤架、咬架和刮板输送机上窜等问题，采取“先短后长”调斜与“先长后短”调斜交替进行的方式，利用辅助设备控制刮板输送机上窜等措施，实现了该工作面顺利转采。

Abstract: According Gongwusu 011,604 mechanized caving coal face long after the inflection point of unequal length, two-lane inflection adverse conditions different heart, using the tail plus stent over inflection, tone diagonal segmented head humbly turn mining methods, and for the transfer mining oblique rotation appearing crowded planes, bite planes and scraper conveyors slide up and other issues, take the form of "first long and short" tune oblique and "long after the first short" tune inclined alternately, the use of auxiliary equipment control blade Upward conveyors and other measures to achieve a smooth transfer of the mining face.

Key words: Long mechanized coal face with putting the top of the coal, Rotary Mining, Inflection, Humbly segmented oblique tone, After a short tune before long oblique
