断层落差和断层面与采面的交角,是影响采面效益的主要几何参数。回采作业的实效往往应决定于断层影响带内外技术经济指标的比值。在巴甫洛格勒煤炭联合企业的一些矿井条件下,确定了断裂带交角λ和综机生产效率之间的关系式为:QH/Q=0.0001λ~2+0.013λ+0.047 (1) 式中:QH和Q——分别为断层带之内和断层影响带外的产量、 分析与断层有关的采面一月数为116个。这些过断层的工作面用的是由1K-101和MK-67型采煤机组成的《顿巴斯》机组、最有利的断层交角在40°-80°范围内,角度愈小,受断层影响的工作面长度愈大、在交角接近90°时,断层带在工作面中的位置不变。这样,采面中综机在垂直面上的调整要简单一些,但顶板管理却复杂化了。
The fault drop and the intersection between fault plane and mining face are the main geometric parameters that affect the benefit of face. The effectiveness of a mining operation should often be determined by the ratio of technical and economic indicators both inside and outside the area affected by the fault. The relationship between the angle of intersection of fault zone λ and the production efficiency of a complete machine is determined at some mine conditions in the Pavlograd coal complex: QH / Q = 0.0001λ 2 + 0.013λ + 0.047 (1) Medium: QH and Q - are the out-of-band production volumes within the fault zone and the fault respectively. The number of January facets related to the fault is 116. These overburden faces use a “Donbass” unit consisting of a shearer model 1K-101 and MK-67. The most favorable fault angles are in the 40 ° -80 ° range and the smaller the angle, The greater the working face length affected, the position of the fault zone in the working face will not change when the crossing angle approaches 90 °. In this way, face machine in the vertical adjustment of the plane to be simpler, but the roof management is complicated.
