Practices on Alignment of Fully Mechanized Top Coal Caving Mining Face with ZF4000/16/28 Hydraulic Powered Caving Supports
Abstract：In order to ensure the normal pushing forward of the ZF4000/16/28 powered caving supports during the alignment process and to have no influences to the face production,according to the poor alignment capacity of the powered support and the alignment difficulty,the special measures were pre-conducted,the alignment percentage was determined,the tight alignment plan was set up and the rational reconstruction of the powered support was conducted.With the enhanced management of the production process and the powerful technical measures conducted,the normal pushing forward of the coal mining face was ensured during the alignment period,the raw coal recovery of the coal mining face was increased by 30 000 t and the month production of the coal mining face reached at 86 000 t.
