1.1 Environment in blasting area
The construction of a wastewater treatment sewage pool needs be modified; opening 16 holes at the bottom of the concrete wall in the sewage pool and the pool wall, the hole is used for water. The environment surrounding the sewage treatment pool (shown in Figure 1) is more complex as follows: the work shop in the north is 5 m apart from the pool; an incinerator in the west is 10 m apart from the pool; mechanical facilities are close to the pool in the east; control room is close to the pool in the south. And so the blasting is difficult.
