针对神南矿区张家峁煤矿常家沟水库周边4-2煤层大规模开采现状，将保护煤柱从防隔水功能上沿宽度方向划分为矿压影响区和有效隔水区。分别对矿压影响区宽度和有效隔水区宽度进行现场实测和理论计算，得出张家峁煤矿常家沟水库周边4-2煤层开采保护煤柱合理宽度为25 m。
針對神南礦區張傢峁煤礦常傢溝水庫週邊4-2煤層大規模開採現狀，將保護煤柱從防隔水功能上沿寬度方嚮劃分為礦壓影響區和有效隔水區。分彆對礦壓影響區寬度和有效隔水區寬度進行現場實測和理論計算，得齣張傢峁煤礦常傢溝水庫週邊4-2煤層開採保護煤柱閤理寬度為25 m。

According to the current large scale mining condition of Changjiagou reservoir surroundings 4-2 coal seam in Zhangjiamao coal mine, Shennan mining area, the protection coal pillars have been divided into mine pressure affected zone and effective water proof zone across their width direction on the basis of the water proof function. The process of field measurement and theoretical calculation about the width of the mine pressure affected zone and the effective water insulation zone has been implemented and the reasonable width of the 4-2 coal seam′s protection coal pillar has come to be 25 m.
