一、本规程编制依据

本规程根据《矿井开采方案》、《矿井地质说明书》、《小煤矿安全规程》以及本矿其它规程及措施所编制。

二、概况

三、地质

四、工作面特征和储量

五、采煤方法及工艺

1、采煤方法选择

（1）选择依据：

根据煤层地质赋存条件，我矿的资金、技术和井下实际情况，采用走向长壁式采煤方法。用单体夜压支柱支护，工作面用刮板运输机运输，进风巷用矿车运输。

（2）采高的确定：

因煤层最大厚度2.8米，伪顶厚0.5~1.5米，目前我矿采用最大高度为3.15米的单体支护，一次采全高。

2、回采工艺

①、落煤：

a、落煤方法：人工钻眼，放炮落煤。

b、打眼工具：127V电煤钻

c、炮眼布置示意图：

d、装药结构图：

e、爆破说明书：

f、一次起爆长度的确定：

工作面长为115米，每日进一档，即一个班必须起爆38米。但每一次起爆长度不得超于10米。炮眼深1.2m，一次爆破进度为1.2~1.3m。

②、装运煤

a、装煤：人工装煤；

b、运输机型号选择及移置方法：

工作面用SG-420／30N型刮板输送机一台，运输巷用SG-420／30N输送机一台。SG-420／30N型刮板输送机用单体支柱移动

c、运输流程：

车场

主提升巷 地面 ③、采场支护：

a 、工作面支架及顶板管理方法

对采场顶板管理最大为四排支柱管理法，最小为三排支柱管理法，即见四回一支柱管理方法。最大控顶距为5米、最小控顶距为3.6米。 支架采用单体液压支柱、绞接顶梁接顶的支护方式。

b 、初次放顶

对采空区管理：用密集支柱截顶，当截顶无效时，强制放顶，初次放顶步距8～

12米时进行。

强制放顶由准备班人员在密集支柱边打一排2米深的孔装药放炮，给顶板形成一个垮落面。

强制放顶前,根据矿井实际回采经验总结,必须将支护方式缩小为最小控顶距,确定为“两、三排”管理,待顶板稳定后再恢复“三、四排”管理

3、采面工程平面布置示意图:

六、循环作业组织形式及

设备配备表

1、循环作业组织形式：二采一准；即二班采煤，一班为采煤作准备。

2、循环作业图表

3、劳动组织

4、主要设备工具配备表

七、主要技术经济指标

八、通风

1、风量计算

（1）按沼气涌出量计算：

Q采＝100¬Q绝¬K采通

100¬1.5¬2.0＝300m3/min；（2）按工作面温度计算：

Q采＝60¬V采¬S采

60¬0.8¬6.0＝288m3/min （3）按一次起爆最多炸药量计算：

Q采＝25A

25¬12.0＝300m3/min

（4）按工作面同时工作最多人数计算：

Q采＝4N

4¬25＝100m3/min

（5）按风速进行验算：

a、工作面最低风量：

Q采小≥0.25¬60S采

300m3/min≥15¬10.92＝163.8m3/min

b、工作面最高风量：

Q采大≤4¬60S采

626.25m3/min≤240¬13.52＝844.8m3/min
