The Portbank colliery in Witten is a former hard coal mine . The mine was in operation between 1737 and 1749 before it was awarded . It marched off with the Franziska colliery . The mine was operated on the south wing of the Helenenberg.
history
The beginnings
On December 16, 1749, the approval for the Portbank mine field was lodged. Baron von Mirbach and Baron von Bentnick appeared as mother . From 1750, there was a long-term court case between the sole trade Freiherr von Recke auf Haus Witten and the mining authorities . The reason for this process was the refusal to pay the tithe by the mine owner. In 1751 the mine was still in operation. The tunnel mouth hole was located between the Ruhr and today's railway line, about 300 meters east of today's Ruhrstrasse. On February 4, 1752, the Längenfeld Portbank No. 2 was awarded . This award was given as a supplement to the first award, as the first award had been lost in the meantime. In the years 1754 and 1755 the mine was in deadlines due to lack of sales . Since the Recke trade had meanwhile paid the necessary mining taxes to the mining authority, the Längenfeld Portbank No. 1 was awarded around 1755. From 1758 the mine was in operation again until 1762. In 1772 the mine field fell into the mountain free . Nevertheless, the mine continued to operate. In 1775, Mr. Sunthum was a representative for the Portbank Union . The mine was measured on April 11 of the same year . In 1780 the mining right for the Portbank mine field was awarded to the district judge Boelling from Bochum.
The further operation
On July 22 of 1784 the mine was by the head of the Mark Berg Revieres, the Baron von Stein , navigate . The Portbank colliery was one of 63 mines that vom Stein used on his journey through the Brandenburg mountain area. At the time, the Cortbänker shaft was in operation at the mine. The shaft was sunk to take up several tons , it had a depth of 73 meters and was used to lift the shaft . A reel was available for conveying the goods with a chain . The reduction of coal took place in the seam Geitling. The seam Geitling was schrämen divided into two parts and then the carbon was then in recovered . Vom Stein gave information about the further condition of the mine in his protocol. In particular, he criticized the fact that a chain instead of a hoisting rope was used as a support means . He advised the trades to buy a new hauling rope and replace the chain with it. From 1796 the mine was idle. After the pit box by Franziska Erbstollen solved was, the mine in December of the year 1798 has been put back for several years running. From the year 1800, the dismantling was moved to the area of today's Wetterstrasse. In the period from 1804 to 1806 an English wagon line was laid on the mine. With the system, wagons with a capacity of three rings of coal were moved through the tunnel. In 1811 the system was 900 meters long.
From 1815 coke was also produced in the mine . In 1817, the Portbank trades wanted to operate the facility with larger cars instead of small cars. They therefore had the system checked by Obersteiger Faust and shift supervisor Bockau for possible improvements. The two experts advised the trades to replace the English wagon control with a German wagon control. This system was able to move carts with a capacity of four rings. In 1826, the Boelling trade applied for the right to inheritance in order to remove the Augustus pit from the south wing of the Augustus colliery . On August 4th, 1826, a length field was awarded for mining in Geitling Flöz . At this point in time the conveyor tunnel was already 1,300 meters long. In the same year the right to inheritance was granted and confirmed by the chief miner in Berlin. This led to years of legal dispute with the Franziska mine. In 1827 the mine was again laid in time limits. In 1828 the Erbstollen was dismantled together with the Portbänker . At that time, the Portbank mine was operating the Carl shaft and the Portbank shaft, as well as a weather shaft on the Parkweg. From January 1832, only maintenance work was carried out on the mine.
The last few years
In 1833 the legal dispute before the Mining Court between the Portbank colliery and the Franziska colliery ended to the detriment of the Portbank colliery. As a result of the ruling, the Portbank colliery now lost the right to inheritance and had to pay the money it had received from the Augustus colliery to the Franziska colliery. In 1835 the mine was marginally operational. In the following year the mine was again within deadlines, the pit water was drained via the hereditary tunnel. Also in the years 1838 to 1840 the mine was in time limits. The mine field was opened by the Franziska Erbstollen. In 1840 the mine was acquired by the Portbänker Erbstollen . In 1846 the Portbank colliery was closed. On March 12, 1859 , the mine consolidated with other mines to form the Borbecker Tiefbau colliery.
Promotion and workforce
The first production figures of the mine come from the years 1737 to 1749. During this period, an average of 3552 ringlets were produced annually . In 1784, two tusks were employed on the mine, extracting 23 ringlets of hard coal per day. In addition, four reel workers were busy with the extraction. In 1830, 18,361 Prussian tons of coal were mined together with the Portbanker Erbstollen . The workforce fluctuated this year between nine and 14 miners . In 1833, 1,372 tons of Prussian hard coal were mined. In 1835 the production was 928 Prussian tons. In 1838 two miners were still employed at the mine.

Remarks
- ↑ The seam in the area of the Helenenberg collapsed to the south by 55 gons . In the area of the Portbank field, it was 1.7 meters thick . (Source: Gerhard Koetter: Steinkohle unter Witten. )
- ↑ Steel ropes are easier to handle than chains. In Vom Stein's opinion, the use of a hoisting rope saved the need for a delivery servant. (Source: Kurt Pfläging: Stein's journey through coal mining on the Ruhr. )
