摘要：为保障榆树坡矿采掘工作面的正常接续，通过数值模拟、工程实践等手段，开展特厚煤层回采

巷道迎采掘巷围岩控制研究。结合矿井生产地质条件通过数值模拟分析综放面开采超前压力分布规律，

据此确定合理的迎采掘巷补强支护范围为距邻近工作面+65～−170

m，在原支护基础上设计补强支护措

施和参数，工程实践应用成功实现了迎采掘巷围岩的有效控制。

is

carried

out.

Combined

with

the

geological

conditions

of

mine

production,

the

distribution

pressure

on

fully

mechanized

caving

face

is

analyzed

by

numerical

simulation.

Based

on

this,

the

reasonable

range

of

the

is

determined

to

be

+65～−170

m

away

from

the

are

designed

on

the

basis

of
