Emergency Coal Mine Flood Plan

High space-use rate, can be stored in containers on the coal mine field. Lightweight, convenient to move and transport. Easy

Background Introduction

For the first quarter of 2010, sixteen coal-mine accidents occurred in China, resulting in the death of 118 people and a direct economic loss exceeding 500 million RMB.

In 2009, more than 1,300 coal mines were closed due to accidents.

Plan Illustration

High pressure bearing capacity, high transportation efficiency, can support high-power water drainage in a flood emergency.

TPU hose is suitable for deployment and use in narrow mine shafts and is very convenient and quick.

Super-high wear resistance, long service life even when used in situations with narrow and complicated terrains.

Lightweight, can be coiled down, quick and easy to transport, suitable for quick response and emergency deployment when accidents occur, which is extremely important for responding within the 72-hour window of opportunity immediately after a coal mine flood accident occurs.

Suitable for use in a variety of terrains, can simultaneously pump water and support far distance water drainage.

Emergency Water Drainage—Comparison

Item	nominal bore diameter (mm)	working pressure (Mpa)	unit weight(Kg/m)
TPU Hose	φ150	1.6~4.8	2.0~3.0
Seamless steel tube	φ150	1.6~10	30~50
PVC HOSE	φ150	0.4~1.0	0.2~1

Compared with a traditional steel hose, the weight of the TPU hose is 10 times lighter. Compared with a PVC hose, the working pressure of the TPU hose is 3 to 4 times higher. The discharge rate is increased, while the length of time and labor intensity required to deploy the hose are reduced.

Emergency Water Drainage—Others

The TPU hose can also be used to supply emergency provisions, such as drinking water and powdered food, to the bottom of mine shafts when an accident occurs.

Telephone wires can be paired with the soft TPU hoses to provide communication between the top and bottom of the mine shaft.

If a landslide occurs preventing large-sized floating pumps from entering the mine shaft, we can provide negative pressure hoses to dip into the water in the bottom of the mine shaft and connect with pumps on land to drain the water.

Emergency Water Drainage—Specifications

Standard configuration includes interfaces. A diving pump, floating pump, and other equipment can be provided according to user requirements.

  

Emergency Storage—Collapsible TPU Tank

High space-use rate, can be stored in containers on the coal mine field.

Lightweight, convenient to move and transport.

Easy to use, easy to deploy and retrieve, short deployment time, can rely on manpower alone to accomplish deployment under emergency circumstances/situations.

Vehicle transportation tanks can be placed directly on a truck to quickly solve the problems of transportation capacity and storage mobility.

Emergency Storage—Tank Material Options

The above specifications are for the TPU tank; specifications for the PVC tank are available upon request.
