A great deal of depression is distributed over The Huang Huai Hai alluvial plain, based on watersoil condition, they are divided into three types--Sand depression, Salinezedmarshed depression and Salinizated depression. The Bei QiuWa belong the last one.A common characteristic in these depress ions is that drainage of ground water isn't unimpeded .Because there is difference in water Soil conditions, used transform way is different too.The paper Shows that full irrigation for flushing salt play the great role in Salinen-alkali soil transform in Bei QiuWa . Velocity of flushing Salinen is rapid, effect is extremely marked .Flushed salinen content in the lowest part can't be drained a way through ground water.Based on the Situation, the paper poses model about harnessing depression Salined-alkali soil, Which dig a lot of non-complete phreatic water wells to pump salt ground-water to reduce groundwater table to empty out ground starage capaity, then, diverting lower minelization surface water flush salinity in soil.The paper calulated affective radius on single well, quantity of pourings out water, adjustable reserves of ground water and adjustable salinity reserve of ground water.

The air inclined shaft is 1.2 m in diameter, 79 m in inclined length and 78°36'49" in slope angle. Before raising, machine chamber for setting raise boring machine and mucking chamber were drived. Machine chamber at upper roadway of 811.4 m level has a section of 4×3.2 m and is 10 -11 m in length. Mucking chamber at lower roadway of 731.9 m level is 8.7 m long and has a section...

A air inclined shaft at the 33rd panel of the 12th coal seam, №.4Coal Mine, Yangquan Coal Bureau was drilled by raise boring machine. The air inclined shaft is 1.2 m in diameter, 79 m in inclined length and 78°36'49" in slope angle. Before raising, machine chamber for setting raise boring machine and mucking chamber were drived. Machine chamber at upper roadway of 811.4 m level has a section of 4×3.2 m and is 10 -11 m in length. Mucking chamber at lower roadway of 731.9 m level is 8.7 m long and has a section of 3.4×2.2m.Mucking chamber was used for setting rock-type scraper loader and mucking when raising. First, guide hole of φ 216 mm was drilled from the low level to the upper level. Then clay flushing and water flushing were carried out. Drilling operation took 5.4 h and average speed was 4.7 m/h.Guide drill bit was dismounted and reamer bit of φ 1200 mm was mounted. Reverse reaming was carried out. Drillings was falling as boring with raise boring machine was drilling. Drillings were moved out by rock-type scraper loader. It took 64 h to complete reaming operation. Reaming speed is 1.34 m/h. Average speed of drilling and reaming operation was 1.135 m/h. It took 3 days to finish inclined shaft raise operation. Construction speed is 7.25 times over speed of construction method using reverse pilot hole.
