The Segen-Gottes-Schacht was a coal mine of the Baron von Burgker coal and iron works . The shaft was located in the central part of the hard coal deposit of the Döhlen basin on Kleinnaundorfer Flur. The shaft (together with the neighboring Neuhoffnungsschacht ) was the site of the largest firedamp explosion in the Saxon coal mining industry. The Röschenmundloch in Niederhäslich is part of the mining monuments in Freital as a cultural monument under state protection.

The Baron von Burgker coal and ironworks began on October 2, 1856 with the sinking of the shaft. The shaft, set at 336.31 m above sea level, reached a depth of 489.94 meters on March 10, 1862 . The problem encountered seam had a thickness of 4.80 meters. In a cross cut , the second seam was encountered at a saiger distance from the first seam of 8 meters and the third seam at a saiger distance from the second seam of 10 meters.
Between 1856 and 1858 a 317 meter long rose was excavated from the Poisental near Niederhäslich . It reaches the shaft at a depth of 126 meters. It was used to supply process water.
In 1866 a gas generation plant was built for personal use. On July 13, 1868, the connection of the shaft to the Hänichen coal branch line , which made it much easier to transport the coal, was put into operation. In 1869 twelve beehive ovens were installed for coke production
On August 2, 1869, a firedamp explosion occurred in the mine field , to which almost all miners on the morning shift fell victim. The total of 276 dead were buried in the Döhlen cemetery and on a specially set up burial place at the Segen-Gottes-Schacht. A monument inaugurated at this location in 1870 commemorates the catastrophe.
In April 1872 the cable car was introduced for the workforce . For this purpose the shaft was equipped with a reel . The hoisting ropes were supplied by Felten & Guilleaume . On November 8, 1872, the Glückauf-Schacht approached the area of the pit field of the Segen-Gottes-Schacht, which had been dammed since the firedamp catastrophe. In 1874, a mechanical coal washing plant was built by Maschinenbau AG Humboldt . A steam engine with an output of 26 hp was used to operate the laundry. In 1875 a telegraph connection was set up between the shaft and the headquarters of the administration in Burgk Castle . In the long run, the gas station on the mine site proved to be too small. For this reason, a gas line was laid from the Glückauf shaft to the Segen-Gottes shaft and fed a newly built gasometer here . On December 12, 1877, the telegraph connection was replaced by a telephone line and a telephone connection was also installed between the filling point and the engine room. In 1879 underground transport with 4 horses was started. In 1880, the flooded buildings of the mine field of the former Potschappler Aktienverein were approached and drained. In 1885, a power station was built in the mine. It was operated with a steam engine from the Philipp Swiderski Maschinenbaufabrik in Leipzig.
In 1896, underground extraction with horses was discontinued and it was replaced by rope extraction driven by a compressed air reel.
In order to loosen the waters of the field to the west, the pumping center of the shaft was demonized by 9 meters and a 226 meter long stretch of swamp was driven.
In the case of a pit fire that occurred in 1904 on the field boundary to the Glückauf shaft, a sludge backfill consisting of washing sludge and fly ash was successfully used for the first time to combat it. In 1906 the shaft was connected to the power station of the Glückauf shaft. After the commissioning of a central coal washing facility at the Glückauf-Schacht in 1906, a 1260-meter-long cable car was built between the Glückauf-Schacht and the Segen-Gottes-Schacht by the company Adolf Bleichert & Co. , with which the clear coals can be processed for Glückauf Shaft promoted. A telephone connection was set up between the two terminus of the cable car. The washing at the Blessing God shaft was then canceled. To offset the charred strut , a flushing installation was commissioned in 1909.
On March 30, 1916, after the stocks were exhausted, the production operation was stopped. The total output over the operating period was 4,199,093 tons. The pump installed on the shaft at the level of the Rösche for pumping process water was moved to the rose mouth hole and the Rösche was dammed up at the shaft. The shaft was then filled with flushing backfill. All buildings and facilities that were not needed were demolished. In 1920 the work was completed with the demolition of the cable car. The large and small district houses as well as the compressor building were converted into workers' apartments. The shaft building now serves as a residential building.
Today the shaft site is used as a residential area "Am Segen".
