Abstract

The utility model relates to the mining gas detection technology and in particular relates to a sponge for protecting a mining gas sensor. The sponge is characterized by being circular or square. The sponge disclosed by the utility model can be used for preventing coal dust from entering the gas sensor; moreover, the changing is convenient, the appearance of a product is not affected and the gas sensor can work for a long time.

Description

The sponge of protection gas in mine sensor

Technical field

The utility model relates to a kind of gas in mine detection technique, particularly a kind of sponge of protecting the gas in mine sensor.

Background technology

In the situation of coal production rapid growth, also bring the particularly serious Frequent Accidents in colliery.The Tenth Five-Year Plan period, 1398 of dead 3-9 people's major accidents occur once in national colliery altogether, occur every year on average 280, account for national all kinds of major accident and play several 11%; 214 of dead 10-29 people's serious accidents occuring once, occur every year on average 43, accounts for national all kinds of serious accident and play several 36%; 42 of the above special major accidents of dead 30 people occuring once, occur every year on average 8, accounts for all kinds of special major accidents in the whole nation and play several 58%.Mainly mining in the coal enterprise of China and the world, to compare gap large for the national security production level.The Tenth Five-Year Plan period, the 1000000 tons of mortality ratio in colliery by 5.07 of calendar year 2001 drop to 2005 2.81, descended 45%, to compare gap also very large in country but mine with the advanced person.2005, coal in China output accounted for 37% of the whole world, and it is nearly 80% that death tolls then accounts for, and the 1000000 tons of mortality ratio in colliery are about 80 times of the U.S., 17 times of South Africa, 10 times of Poland, Russia and India 7 times.Severe safety production situation not only serious threat people's life security and health, also has influence on social harmony and international image.The China's coal-mine overwhelming majority is Jing Gongkuangjing, complex geologic conditions, and Disasters Type is many, and it is wide to distribute, and mining conditions is the poorest in each main producing coal country of the world, disaster is the most serious.In State owned coal mine, complicated geological or extremely complicated colliery account for 36%, and the simple colliery of tectonic structure accounts for 23%.According to investigations, 456 meters of the average mining depths in big-and-middle-sized colliery are adopted dark mine output greater than 600 meters and are accounted for 28.5%.Little colliery is on average adopted dark 196 meters, adopts the dark mine output that surpasses 300 meters and accounts for 14.5%.Gas Disaster.In the State owned coal mine, gassy mine accounts for 21.0%; Coal and gas outburst mine accounts for 21.3%; Low gaseous mine accounts for 57.7%.In local state-owned coal mines and the Township Coal Mine, high gas and coal and gas outburst mine account for 15%.Along with the increase of mining depth, the increase of gas emission, the ratio of high gas and coal and gas outburst mine also can increase.The China's coal-mine hydrogeological condition is comparatively complicated.In the State owned coal mine, hydrogeological condition belongs to complicated or extremely complicated mine and accounts for 27%, belongs to simple mine and accounts for 34%.In local state-owned coal mines and the Township Coal Mine, hydrogeological condition belongs to complicated or extremely complicated mine and accounts for 8.5%.China's coal-mine water damage ubiquity, big-and-middle-sized colliery have more than 500 workplace threatened by water damage.In little colliery, nearly 20,000 places, mine 900 many places of gushing water danger are arranged, account for 4.6% of sum.

To mine safety in Gas Disaster, normally " take out afterwards first adopt, monitoring, with the wind fixed output quota " the control of coalmine gas working policy, but because the thought of the heavy output that many enterprises exist, light safety, and the miner is too low to pacifying individual right to know, detected gas is exceeded standard can not get paying attention to, the miner can not make quick action to the very first time gas situation of exceeding standard, and makes can not implementing from basic unit of can not managing safely, causes the coal-mine gas disaster constantly to occur.

The first-hand resource that occurs can not in time support in the control ore deposit after the mine disaster also is to cause an important component part of coal mining accident extension.After mine disaster occurs, Communication Block under the ore deposit, the personnel's distribution situation under the ore deposit can not clearly support control, makes decision-making cannot take out best scheme.

Detecting methane gas by firedamp sensor also takes precautions against rapidly, as placing firedamp sensor by mining illuminating lamp, gas is detected, but because firedamp sensor is operated in the colliery that produces a large amount of coal dusts, time has been grown can affect measurement because dust is attached to firedamp sensor, changes firedamp sensor and can bring the inconvenience of use.

Can prevent the above-described problem from occurring although in the patent of having applied for, disclose a kind of technology, owing to adopt adhesive sticker to add respiratory membrane, use for a long time, except adhesive sticker can affect the outward appearance of product, also can affect and change respiratory membrane.

Summary of the invention

The purpose of this utility model provides and a kind ofly can prevent that firedamp sensor from entering coal dust, changes outward appearance convenient, that can not affect product, can make for a long time the sponge of the protection gas in mine sensor of gas in mine working sensor.

The purpose of this utility model is achieved in that the sponge of protection gas in mine sensor, it is characterized in that: sponge is shaped as circular or square.

Described sponge and gas respiration channel are flexibly connected.

Described sponge size is identical with the firedamp sensor bore.

Described sponge shape is less than the firedamp sensor bore.

The beneficial effects of the utility model are: because the gas respiration channel of placing sponge is arranged between firedamp sensor and the housing, gas respiration channel and the sponge of placing sponge are flexibly connected.Can not affect like this firedamp sensor and detect methane gas, change outward appearance convenient, that can not affect product, can use for a long time.
